Apparently the focal point is the head, but its dead center. There is a lot of empty space which just doesn't lend itself to this photo...I would suggest pulling back a tad, placing the head of this dragon around the fourth sector (if you want to follow the "Rule of Thirds"), the wings should (IMO) go from 5th sector to 3rd sector....the legs should be around the 7th and 8th sectors...
Or something like that....if you don't understand what I'm getting at...make a "Rule of Thirds" grid and number it 1 - 9 starting at the top left and working your way from left to right, left to right and finally left to right....
And obviously, by no means, are my ideas written in stone...its your eye after all, not mine...
