I remember putting this comment aside to reply to, but... I guess I never got to it. >_< Sorry this is so belated. And being belated, I can't remember what I was going to say.
I'm pretty sure it was only two layers. I know it was a doodle that just kept going. There were a few times I almost trashed it. So I think by the time I got the comment there was nothing I could have done to edit it, though I liked the idea. :)
This is really nice, Klawzie. Nice lighting, good colors, good fabric...
Hm...If you have the lines on a different layer, you might want to consider tinting them a different color (dark brown or blue, maybe?). I think it'll help soften up the look, and give it an overall smoother feeling.
