Similar things I’ve said on here apply to yours, you may want to check the post out:
Anways, the character seems a little flat shaded, make sure you’re using the cycles rendered for more non-bias shadows/contrast. Lighting and composition are quite important.
Make sure the person can glance at it and say, “yup, they’re applying for a center”.
Also copyright is no joke. Avoid using copyrighted materials like logos and brands from big lads like Walmart and Target (examples). Give it the sense of an application center, all I’m seeing is the person looking at a phone with the roblox logo.
Maybe a person looking at a clipboard writing down things essentailly applying. Also, give expressive looks and feels, exaggerate motion.
Make the camera closer, it also seems a little too far away, don’t worry if the horns clip out or anything, its needed for composition.
TL:DR
Composition, readability, lighting, and posing needs work. Overall, pretty good on your first gfx, continue gfxing and I believe you can 1up yourself
