cool, you might be jumping into to high a subdivision level, you could also try a new(not so new) process and use shapes to make the parts then adjust each them merge each in to the body to get a better understanding of how you want it to look and it's easier to stylize the area's you want to.
Talking about this one:
Here tutorial
It will help a lot and you can get a good base to work from on future projects.(as long as you continue to refine it throughout your 3D journey)
Nice progress so far, if you decide not to do the tutorial and model, you have to go down a some subdivisions add details and then go back up rinse repeat.
