Cool (pun intended) and nice work. Better in full view. Just a suggestion, though: make the sky a bit darker (especially its bottom-half part). It's just my personal taste, but I think that the dragoon would look even better then. The castle may need more contrasts too (slightly), in my humble opinion, of course.
Now you're chopping, girl. Dragons, my favortite. This is quite beautiful
that was so nice burntfaery , keep going
