I'm in the process of creating a template of sorts for the running character in my game, Subject 33.

Since I want the sprite to look like a real human running as one would, I'm going to make a set of frames using line segments to represent each limb as it would look when the character is running.

However to accurately do this I've ran into a tools wall. I'm not sure what to use. If I do it by hand in Paint or Photoshop, it'll take forever trying to get the limb lengths right and redrawing all the angles required, etc...

What might make this easier is if I had an overlay of the original image that I'm using for reference. This one.

3ds max, might be overkill as I only want to draw and rotate line segments to match human movement to be eventually drawn over to make the actual body, arms and legs, head, etc that will make up the character.

Anyone have an suggestions or things that might make this simpler?
