Ponder Studios’ Blenderella tutorial series is now available on youtube (I’d put it on x0.25 speed during the timelapses because they’re FAST and it’s hard to follow). CGCookie’s female character modeling series isn’t in a neat little playlist but I think it might be easier to follow, there’s also a face topology breakdown here. You can find both of Dikko’s tutorial series here, and there’s also this series by Tomcat , which I’ve seen people get good results doing.
Watching FlyCat’s timelapse videos can be educational too - and this one is all poly modeling.
