This is nice. I like that...timpany? The bass beat going on...nice and that part that repeats (can't think of the right word for what you'd call it...but it's the part at the beginning). The only thing that bothers me is the...chimes...I think they're too prominent and you should quiet them a bit.
I would love to do some film/game scores too. I'm more limited than you. I don't have anything that sounds as orchestral as this sounds. I bet this would sound really cool with a large orchestra in a nice studio. I often wish I could have an orchestra playing my music.
