Whoo! My first correction as a corrector for
! Sorry if my handwriting is a bit messy.
A few notes for the original artist,
: I noticed you saved this as a JPG file, which probably explains the poor quality of the lines. For better quality, ALWAYS SAVE AS A PNG FILE. They take up more space, but they're so much better to look at. Don't worry about interlacing it, just save as a non-interlace PNG and it'll still be tons better than a JPG.
You actually did a really nice job with this, there wasn't much for me to correct. You made the abdomen too thin in comparison to the ribcage, however. And the left pectoral protuded a bit too far. There was also something weird going on with the hips. But apart from that, it was pretty well-done.
And also, always remember to draw nipples. There's nothing dirty about them, and all men have them, so if you're going to make something anatomically correct then remember to include them.
