First of all, I'm kinda new on this stuff too, so don't take all I will said for truth. In fact the best I can do is suggest you to find anatomy reference from art books or free resources on the net, there is a lot
First impression is that the proportions seems rather nice, so good job on that. My second most impression is that your back does not have the same reading as your front. Its seems less precise. So I think you should do some more work there to get it on the same page as your front.
For the front here are my thoughts. Again, I'm a really new on the anatomy stuff, so I might be mistaken, take more advises and cross everything with references.
1. You should mark a bit more the major form of the rib cage before detailing, some plane changes might be missing.
2. Be careful with the pecs. Its has three major sections. First one comes of the calvicle, on the first third. Your bony section should be a bit more covered by the muscle. You see a bit of the clavicle with a landmark depression before the front deltoid section, as you can see here :
The start of your clavicles seems a bit over-pronounced to me.
I've drawn some messy stuff about obliques and seratus, not really good, forget about that.
3. Your abs seems a bit too much symmetrical, abs are never symmetrical, like a lot in nature. Be careful with the last "2 packs", its more a single one, with fat, even on skinny / muscle guys. Some nice planes to work on with the pubic fat in fact.
7. Your deltoids seems to lack the front part which cover more or less the last third of the clavicle.
Here some first impressions, hope it helps, and again, don't take me on words, cross everything with careful studying of anatomic references.
Its a nice start, keep it going
Edit : Forgot to talk about the sternomastoid muscle. Its goes from the back of the ear to the first third of the clavicle and the manubrium (upper section of the sternum). So it has 2 insertion points. And your origin feels a bit misplaced on your "neck".
I would suggest to invest a few bucks on a good anatomy tutorial. I recommend Rafael Grasetti's Anatomy Tutorial Package. https://gumroad.com/grassetti It is kinda condensed though but he covered the whole body and face. If you want a really indepth lesson, try Ryan Kingslien's Anatomy 2.0 course.
Gevz is absolutely right. Grassetti will fast track you to anatomy 101. If you need a more interactive approach to learning I'd suggest another phenomenal arisit, Scott Eaton. He as a app on ios devices called L'Ecorche. Very cheap resource. https://itunes.apple.com/us/app/lecorche/id515026024?mt=8
Outside of what was said above if you want to say, practice the torso. Try extending the arms, hips, neck to head to have the extra mass to sculpt off of. The human bodies muscles inter web with synergy. Sometimes you may sell yourself short on proportions and how things inter lock because you cant see how it ties together.You can always hide the parts to display just what you want work. But this is just me personally. ;O

All the best!
