advanced rendering for AutoCAD
It is a good start. The perspective match is nicely done. The only thing that strikes me was the different sun angle on the model and on the real environment. In the real photo sun is coming from the back left to right, on the pasted model is from front right to left back. Also it would be nice to have slightly bigger picture :)
Wish my photomatching where half this good!
My too hahaha... :D
