That was no where near logical. and it wasn't even a funny kind of illogical. /backontopic. The cup in itself is bad. its a 3d cylinder, with a 3d handle. meaning you could have shaded the handle. and your shading is just bad. the fuck man. second. If you cant draw a background dont fucking use some random clip art. oh god this would be ten times worse if there was no background. I would suggest penciling shit out on paper(if you know how) and scanning it//taking a picture and transferring it to your comp, because the linework on this is just BAD. The skull is slightly better since there isn't a disgusting rusty background or whatever. but you still don't understand shading. shadows don't do this. just putting this here cause you obviously need it : Light comes from a source usually above your object, meaning that shadows are cast in the opposite direction of the light.
