I really like how you have drawn the plates, especially how they at certain places seems to overlap each others.
I am not an expert at these things, but what I recommend is to read more about the subject. when I started out I read more about it on this website. http://www.platetectonics.com/book/index.asp
I think it explains the basics in a quite simple and understandable way.
I would like to test and draw the movements, but sadly I don't have the oppurtunity for the moment. But as I see it, the Green plate (with mountains) should move towards the light blue plate and form a Continental-Continental Convergent boundary. I believe other members at the guild could provide more accurate and better info than me :/ there are also plenty of other threads here on the forum that brings up the subject!
