I was hope I could get some guidance on the abs and back or any other area someone thinks needs improving.

Hey, post the image here in the thread so we can see it.
Also if you are struggling with muscle anatomy - check out some bodybuilding photos online or get to the gym with your sketchbook, most guys won't mind throwing out a pose for you to get the form right.

EDIT:

My bad, the image took a while to turn up..

I think the abs are good, but if he had Traps that big he would be hunched forward a bit more - also give his chest more depth to balance him out a bit. I think you are missing out on Vastus Externus detail in the upper thigh as well...
