It looks pretty good. However there are a few notable issues I felt I should point out.
1: His left arm is thicker than his right
2: His left leg is longer than his right
3: Lines should be much thinner. Keeping lines one constant thickness gives it a feeling of sloppiness usually, and to top it off, they are awfully thick for the size the picture is. Try not using the same constant thickness and it may help. Also try tapering lines.
4: Coloring? I was never a fan of unfinished work, I'd rather see something finished than something that is just the main sketch or linework.
I don't have a problem with the 8pack because it is possible to have one. Anyone who knows about muscle structure would know this as well.
As for other members, and well everyone.. Who gives a stuff if somebody is a furry fan or not.. Just post the damn drawing, don't make a big statement or disclaimer. If people give you unjustified stuff for it, then they are not good people, end of story. Everyone has something they enjoy, and if those people don't like that, the they shouldn't be on the internet. I'm sure we all have something we enjoy that others may not, and to give somebody stuff just because they enjoy that one subject, is just showing others that you are a handicap.
Overall, its a good drawing, just needs a few fix-ups and it will be much better and more enjoyable.
