You can avoid the "gradient shading" by using more contrasting colors and less colors total as well. It might look wrong close up but when you zoom out it looks good.

So you think that you "hate" your work, we're gonna suck you off and tell you it's beautiful?

I don't hate my work. Im just not good at it

Okay thanks that helps

Whoa dark shading on the box and door. The shading doesn't flow well at all. Look at the top right corner of the door. Does that look right to you? The window pane utilizes better color choice and shading.

oops i messed up ill fix it soon

here is an update on the box and the door

The design seems too simple, make it look more unique and don't forget to shade.

Okay
