That is no troll I'd ever want to ride. The detail on this is amazing, and extremely overwhelming (in a great way). It's a little soft and fuzzy perhaps for the focus, but I do like how that draws your eyes to the rider and the ridiculously muscly arms on the troll. I also love how you've got the texture to the toenails (is that what you'd call them?). Excellent work! Absolutely beautiful detail.
