Probably, blokes are really much more thickset by comparison though. However, the basic musculature is the same so I suppose if you made the muscles bigger, anatomically it would still work. If you wanna draw a bulked up guy I'd recommend making the head fit into the body 10 times (rather than 8) and make his neck very thick too.
10 times? what would i have to elongate in that case? the torso region or the legs? i usually work with the 8 heads proportions system, so this is a bit new to me. also, if i include a woman in the drawings, should i make her 8 heads or more?
Yeah, if you make the body 10 x the size of the head it gives the impression that the head is smaller. It also depends on what kinda guy you're drawing. If it's a heroic type I'd say make the torso 3 heads the gap between the waist and the crotch 1 head maybe and the legs 5 but if it's a squat thick set hulk type, make the legs shorter and the waist wider. It's difficult to explain without showing you, if I get a chance I'll perhaps have to do a tutorial or sketch dump explaining it. The Stage 5 Escalation pic in my gallery is an example of a 10 head high character if that's any help?
