Thanks a lot @sicaeth, @Kreyhardt and @rgdraw !
I developped a bit my characters story and that girl will be a bit more focused on. I imagine her being an orphan aswell and finding the raptor in an oasis, I'll draw her a bit more and find her typical old arabian clothes

first thumbnails to brainstorm, I usually do my thumbnails with lines more than with shapes, so it's a bit sketchy ^^" !

thanks !
color test of the side character with her battle outfit

@mavkrogan thanks a lot !! to be honest I already had an interview/portfolio review with Disney and they liked my art and showed me support, it was super inspiring ! my goal in life is to work on an animated movie or create my own
my artstyle is more cartoony and I had many insecurities with this kind of contest ! But I'm having so much fun, theses characters really inspire me !!

I sketched a bit the look of my concept art sheet, that will be my last art for today, I need a break, I have draw a bit too much in just one day hehe

thanks you two !! I really appreciate your support
What do you think about that design ? is that epic enough for this contest ? Not out of the theme ? I was a bit afraid this morning about it D:

I'm not done yet tho ! I wanna render that character concept board I'll start the illustration when I'll be 100% happy with the concepts and researches !
