First, understand that I am working with some really primitive tools.
This is the head of an animal called Syndyoceras, which lived in North America during the Miocene Epoch (I think). It resembles a pronghorn antelope, but is actually more closely related to camels and llamas, and probably had a somewhat mooselike nose. For fighting, males had an odd arrangement of horns as well as enlarged canine teeth.
First, I sketched the head with a ballpoint pen, using as a guide a photo of the animal's skull, with photos of the heads of camels, giraffes and moose as fiurther references.
Second, I scanned it. The result was the "initial sketch" (see other drawing). I was pretty disappointed in that. It was a very sketchy sketch.
The only image manipulation software I have is Microsoft Photo Editor and Paint -- real basic stuff. However, I tried using the "smudge" tool of the former to blend in the pen lines, and it resulted in a kind of charcoal/pastel/watercolory look, which I decided did not suck too much. I did a little bit of limited corrections in Paint. This is the result.
I don't have a lot of control with this primitive smudge tool, and in some areas I overworked the sketch and lost some definition. But it does not suck too much.
In the future, I hope to get better with this newfound technique, and maybe someday this first attempt will make me cringe to look at. But for now, it's not a bad start. I actually like it.
