Looks great man, I'll defiantly check it out once you are done!
I have made the house and the garden my self!
the whole house and the fence in the back is from this
So I cant make the boxes by my self? I have downloaded the textures and made my own boxes.
The only stuff i have copied is the three and the cars.
The rest is made by me.
It looks like you have decompiled other simpsons maps and just taken parts from each one into your map. Because that tree-house looks like the one from aimcrazyjumpsimpsons (the car aswell)
And those crates looks like those from Fy_simpsons
So far, looks like the best Simpson map out there.
