I used to do that all the time as a kid. My parents were always steamed (pun intended) about it because they said it was wasting electric and letting the cold out of the freezer/refrigerator and going to make the ice cream melt or the food go bad.
No i dont mean it like that, i think the shading it good. It's just as though you've shaded the emotes as if the light is coming from the top left. But you've shaded the fridge as if the light is coming from the bottom right, i can't really explain But i see what you've tried to do
I must say that the first thing I saw here was the awesome detail on the door. I how you put the little metal incasing so the stuff doesn't fall out (classic), and the yellow tard cooling himself on the top looks like he is a partner in crime for stealing stuff lol.
