Heres a couple of skethces of some Wierd Western characters I designed a while back. I must admit I am tempted to have a bash at some more!
Wierd Western Varmints, the Masked Range Rider, Voodoo Lady and Barbed Wire Skeleton
South American Were Creature
I really enjoyed sketching them and really should do some more! I have a whole load more in a sketchbook somewhere and will see if I can fish it out and scan a few more pages!
All the best!
