Actually, what I meant when I was talking about the fridge is that the doors open in 2 different directions, based on handle position, this is usually not found in fridgerators, as it would be inconvenient. You were right to flip it to the other side, but you also should move the upper door's handle to the right now, and it would be more logical.
I suggested a just a little bit on the cacti just to make them less 2D, they looked kinda flat, I know it is a good idea to give background objects less detail, but the cylinder forms are just a bit hard to discern, IMO.
I love the AA and the texture transition to darkness on schemers wall.
