Hey ho,
My Name's Jenna and I'm doing some concept art for a couple of miniatures that hopefully will be released along with the Warlord game. I'll put up a bit of my process here to give you an idea of what goes into a concept. I usually draw game concept art, but the principles are the same.
First up I gather reference for the drawing, because this is based on a pre-existing set of characters, I am looking at the miniatures that have aleady been done, as well as some previous concept art. Here's a page of reference to give you an idea.

Okay, once I have some reference and have got a bit of a feel for the character, I'll go ahead and do some thumbnail sketches, to find a good pose for the character.


I scanned these drawing, then picked on of the poses that I liked, and cut that one out, increased the size, then drew over the top of it to get a base drawing to go on with.

This guy is pretty rough, but I can clean him up later. The important thing is to have a body to draw armour etc over the top of.You can see I drew a profile of his head, as it isn't easy to see in the original drawing, and a sculptor might get angry at me :B
I duplicate this guy several times, then on a new layer in photoshop I draw costume on top.

You can see I've done a few variations, again so there is an option of which one to go on with. I'll post some more later on, it's not over yet!
