I am still working on projecting the image onto the top of the rendered model but normally I don't go into that much detail. So long as I can get a sense of what the 2-D model of the building is like once it's rendered as a 3-D model I'm happy.

You can also adjust the lighting of the new, rendered model within Sketchup. This makes the process of removing such lighting from the original image unnecessary. I'm still working on fixing the dormers on the new model and I'll post some updates here in a bit.

Thanks for the comments.
