Fantastic work!
It's great to see you try different styles and your willingness to do so at an early stage in life. I was very stern about doing detailed, more photo-realistic work for many years after college, and would'nt allow myself the freedom of working loose. Keep your mind open, don't stop working, and I believe you'll reach a level of maturity in your work well beyond your years.
If you ever decide to take time off from your art, PM me and I'll nag you and scare you with my own regrets to keep you working!!!
