I've always considered it a decent program for creating dirty maps to use in other aps, a Quake texture conversion tool and as a wad organizer but I never realy thought the drawing tools had much to offer. After seeing Orl's efforts, I decided to give it a try as a basic drawing instrument. Here is a pic of several steps in the creation of a texture, from fucking around and creating a tile design to an idea for a demon head I've spent the previous two and a half hours working on.

I found that it is possible to fake a dodge and burn in Wally, though it is not an easy process given the fixed nature of the light/dark. The demon here is a pretty nasty piece of work. I took the texture about as far as Wally will go with the bottom image.
So I loaded that one up in Gimp, cleaned up the head and made it symetrical, applied a cyndrical gradiant layer to the head area, and this is the result:

I placed it back in Wally for a reskinning with the Quake pallette.

This image is pretty much ready for use though the higher rez version is still a work in progress. If anyone somehow has an affinity for this little mounted demon head feel free to use it, touch it up, or whatever. There are also some lossless pcx and tga versions of these pics on the site as well.
