Great job! Like the hairs! Really nice hand painting and good bakes!
I do feel the render is a bit dark, might consider changing the light direction so its more on the characters body?
You have to submit a sheet with the initial concept work (drawings) (size 2048 x 2048 pixels)
Also the size of the beauty render needs to be atleast 2048 x 2048 pixels (yours is 889 x 889 pixels)
Even your detail sheet needs to be larger (2048 x 2048 pixels, yours is 889 x 889)
You should divide up your submission sheets and label them as
Concept Sheet

Embedded Marmoset Viewer (you can use if you like!) (20 mb file size limit)
