I love the first one, it isn't too over the top or stereotypical. can't wait to see the game!

Your OC's adorable, though I'd like to know more a bit more about her. You don't have to include a huge bio in the picture, but maybe put a bit about her in the description.

first off, I really like the colors you chose. the backround colors are just dark enough so that they don't clash. You have a cute style, you just need to perfect and tone it a bit. The wings draw away all the attention with the bright gold coloring, and you don't see Zacharie first. Try toning down the colors a bit. Zacharie himself though, seems a bit flat. Try doing some basic shading here and there, to give the character more depth. Don't make the hair so big, it's distracting, and some of your proportions are off. There's more I could advise, but try just going off this. Keep trying, you'll get better.
