Hey! just off the bat id like to let you know that you should probably add an @ to your name, it makes it easier for people to tag you in things and search for your account! i believe all you have to do is go into your profile and enter your the username you want into the box with the big @ symbol in front! :)
Off the bat I can tell shes a very interesting character, though I see a lot of room for improvement and fleshing out. I like that you have given her flaws and limits to her abilities, but I just have a few things I wanna bring up-
Weight;
there's nothing wrong with how much she weights, but I would go in and add the unit of measurement to the end, Im assuming its pounds so I would change it to 135lbs to avoid any confusion.
Identifying Marks;
Its good that you've included this but i would recommend you expand on it more, for example, here is the identifying marks for my character Jack;
notice how I've really gone into detail on minor parts of his appearance and how his backstory may tie into his appearance now and in the future. Something like scars and the upkeep of one's hands and fingers can really tell you about them. Does she have long fingernails that are tidy and well-kept? does she have bags under her eyes from lack of sleep? Little things like that are huge in making a character feel more life-like!
Body Type;
This definitely needs more info. There's not necessarily an "average" body type like there is an average height/weight. Everyone's body is shaped differently. Does she have short legs and a long body? or a short body and long legs? Is she's a princess, has her form been maintained over the years, has she been wearing a corset so her waist is thin and high? Is she muscular? can you see her ribs when she stretches? It really helps the reader/audience get a visual idea of what your character looks like
Eye Colour;
This intrigues me. You said her eyes are Light Pink- why? Does it tie into her abilities? Pink isn't necessarily a "natural" eye colour unless she's Albino, which you haven't described her as being. If Light Pink is a natural eye colour in your world, there's been no mention of it. Also, light pink is a very broad term, what shade of light pink? are we talking baby pink or bubblegum pink?
Predjudices;
I like this. I like that you've given her a negative worldview that can be changed over the course of the story. My only advice is to make sure this worldview influences other parts of her personality. How she refers to or references others that may not fall into that narrow though.
Strengths;
You've given her flaws, which is a good start, but she's gonna need strengths as well. It's a very common mistake to make a character fatally flawed with no redeeming qualities. Everyone has something about them that is positive. A villain may hate humanity but might like dogs, that's a redeeming quality, kindness to animals. She could be loyal, welling meaning; maybe even disciplined. This website has some great ideas, though be sure to think of some yourself!

Necklace;
This could be applied to all the favourites- but why is it her favourite? And if it's important to her character (which it probably should be if it is her favourite possession) then you should describe it little. what metal is it made out of, does it have any pendants or charms, what does the necklace symbolise, or is it her favourite because it's pretty? It's not necessary, but maybe link a reference image? (if its based on an actual necklace)
Puddinland;
What is the meaning behind this name? It seems a little bit odd, if the story isn't something kin to Adventure Time. Im not saying its a bad name, I just think its a little out of place in a story about missing people (unless you're going for a morbid story in a lighthearted setting, but that wasn't really the vibe I got.) Id recommend maybe changing it to something more subtle, maybe taking inspiration from a word that means pudding in a different language, something like Madelend? (like madeleines)
Abilities;
I like that you've got an ability that has limits, but id like to know more. So far all we can tell about the power is that it involves lighting somehow. Does she summon it or does she shoot it from her hands? what do these limits entail really? What are the effects it has on her mind and body?
Overall I think shes a great outline for a character, she just needs a little fleshing out. If I may recommend the Character Profile Thread? I has questions for you to think about things your character you may not have considered :))
