The pizza is blurred intentionally (Depth of field).
The character’s face is also shined on purpose to give it a look of a toy.
This gfx is meant to be simplistic.
Alright but, as I and other people pointed out it doesn’t look that great. The depth of field doesnt really need to be there as it shouldnt focus on just one thing when there is barely anything else in the shot, thats why a lot of GFX tries to avoid depth of field in shots that dont have much in it. nontheless good job
LOOKS S-I-C-K. The only concern I have is the background? Overall looks awesome and looks like a ROBLOX toy! 
Hello! First off, I really love the amount of creativity put into it! I also love the shine that you put onto the character. It looks so unique! However, there’s a few things I’d like to point out. The character’s pose looks a little too stiff. I’d suggest using references when posing the character. Another thing I’d like to suggest is that you have the pizza in an open box. Also, I’d suggest you experiment with the camera angles a bit.
It might be a bit late on this, but it looks nice! I like the layout you did for the pizza man, and the material choices make it more of the theme of it.
I see no change in this, except for some decorations in the background, like tables and pictures.
Nice job! 
I think it’s pretty good, but the pizza looks a little blurry, and I feel like that’s one of the main focus points in this pice. Maybe blurring the wall and floor a bit and enhancing the chef and pizza would help.
