Hey man, keep it up.
Doing the detail of a model is a pain when you start off, but its the detail that gives the model its realisticness (not too sure thats a word!) You'll get there if you stick with it as your basic shapes will come a lot faster giving you time to work on the details.
Try leaving this model for a bit and then coming back to it when you get a bit more into maya and know the toolsets better off.
