Maybe, perchance, please, with your next project save the psd's...those would make an awesome learning tool.
They are actually done in PaintShop Pro version 8.1.
I still have one from the Excaliburs I did, it is a more simple one that I made for Don Dawson to help him learn texturing and layering. The ones from the Excelsior D get pretty complex about the saucer and may not be as helpful anyways. The Detail layers have allot on them but the Glow and Backgrounds can be useful. Normally the more complex ones are not as useful, they will not show erasing or overlays and raster compacting to form a detail(s) area.
PM me a E-mail address and I can send you the one for the Picture below. It is a overly simplified one but it get the point across. It is also one I don't mind sharing as the Excaliburs are a finished product as well as the Blue Fleet I was doing. Only two ships on the Blue fleet are left and have been in a unfinished state for over a year now. Only reason they will ever get done is for Mackie, as they were ships he wanted.
