I found an amazing site to practice anthros/humans: http://artists.pixelovely.com/practice-tools/figure-drawing/

I found it "by accident", while looking through some random drawing tips videos, so I was extremely lucky since I was just in phase of practicing anthros :)

2 minutes per sketch. I'm quite satisfied with result. I did another batch before this one, but this one is much better, so I'll only upload this one. Less than 30 minutes for both batches and I can see improvement... Will definitely do more :)
