Not bad PYRRO your 14 now i take it cause i got to say.
I first started my CG work with 3ds MAX 7 when i was 14 (I'm 16 now) and my stuff did not look as good as that when i started. I think you have great potential to become a 3d modeler, I too want a career in the 3d industry, my only advise to you is go through EVERY tutorial you can find to increase your skills.
This was the first cg render i ever did

Now i am doing 30 min+ movies with great detail and high quality pictures.
So keep up the good work!!
