No, I dont use Dundjinni, although I do have a demo of it. Its all done in the GIMP. Thanks for the tip on the shadows, I'll try to implement the ideas, although I just love shadows and I dont think I'll lose them altogether. The walls I will fix in the way you suggested.

The GIMP doesn't seem to have an inner glow effect but there may be a plug-in out there somewhere.

Thanks for the encouragement.
