First off, 10 minutes isn't going to cut it. Especially with anatomy. You have to spend some time til the form looks right. Even then go back and look at it later and tweak some more.
And the white spots are not just single pixel dots. That always looks bad.
What I found was the proportions were all off to each other. Not by much, but with anatomy, it shows a lot. Legs were too short, neck too thin, head to big, joints in wrong place, etc, etc.
Colors a bit too saturated (That's just personal preference).
Quick edit:
