Your quite the fast one. Here’s some C&C, hope it helps.
>check the stretching on the cheeks of the bulldog. Also try to cover that seam within the texture or vertex coloring.
>Try desaturating your colors a bit, that red almost hurts the eye.
>Same goes for those white pants. They need creases, and most of all they need dirt to make 'em come alive
> Add some shadows around the little details on his chest. Like what you did for the white straps on his chest. Do the same for his buttons and the white horizontal things.
>Variate the color of the collar, add some dirt and shadow.
>Try giving the white straps on his chest some detail, they take up a lot of space and look a bit boring the way they are now.
>Also try adding a little shadow on the underside on of his head. it looks really flat. Also a bit more shadow under his armpits and under his crotch would bring more depth to the texture.
>Try to add some leathery texture to the leathery parts like the bag and straps. The more worn, the better.
You’ve got some time left, so try spicing it up as much as possible.
Good luck!
