Box moddeler.....LOL
I would just work on this character to the best of your abilities try to finish it ( don't worry about how it looks, no one I know has made the perfect model first time around).
What I do encourage is trying to rig and animate it , so you"ll see where the caveats are.
I for one think it's pretty good that you managed to get an all quad (from the looks of it at least) model, no tris or Ngons, double extrusions and son on.
The only thing I would like to say is that you should cut down on the polycounts, you don't need that many to get that shape.

But great start
