Question:

Does anyone have tips on drawing a full body pin up model?

I need to draw a good pin up model who looks a bit like me for a tattoo someone wants.
I'm okay with drawing but I need some real help.
Anyone know of good sites with a sort of step by step guide or does anyone have some tips for me?
Thanks!

Best Answer - Chosen by Asker: Are you drawing from a photo? It's best to
1) measure the proportions of your figure
2) draw the big shapes (eg., big circle for the head)
3) draw your axis lines
4) not draw the details until you have successfully done the above.
