The meat would probably look better if it was darker. Also put some more details in it the meat, otherwise it will just look like some sort of sauce.

lilterror, use flash. flash is for vector art.
ignoring the vector part, its a decent image, it could use some better shading. 7/10

Can you elaborate on the shading problem and tell me how can
I fix it

now this is a huge improvement

Looks much, much better on the parts where it's vector'd.
