One of my more amusing painting faux pas occurred years ago when I was painting up some 15mm WWI Arab camelry. Things were going well, and all looked very nice. As I was showing them to a friend - and I wish I could remember who this occurred to first - we noticed I had painted the camels with hooves. Camels don't have hooves!
Curiously, I haven't painted a camel since, until now for the Sudan project. These three are from Peter Pig's camel baggage train, with two Egyptian handlers. Note the fine detail on the packs. Note the accurate light color for camels of the region. Note the lack of hooves. :)
Right now I have one final British unit almost done, and have started in on the Dervishes that I received from 19th Century Miniatures. Those look very nice as well. Stay tuned.
