Some of these really work for me.

I really like Dragon I, III and IV.  Dragon II and V are less successful in my view and Dragon VI works because of it's size.  So a mixed bag really.  Having said that Dragon III and IV contain a lot of energy and I love the texture and composition of the paint.  I keep these in my office.

I may return to this theme in the future as I don't feel I've really 'nailed' it yet.
