I like the color scheme on the ventral side but I'm not too keen on the dorsal pattern, the trailing edges of the wings in particular. To me, it looks a bit too much like a moth or a butterfly. Maybe either reducing the contrast between the dark and light colored bands or reducing the contrast between the two. Of course, it's ultimately your choice and considering that these will, presumably, come unpainted, I could mine however I wanted, if I were to get one. And depending on price and if I can figure out a decent way of displaying it, I'm seriously considering getting one, even though I'm not normally a big pterosaur fan.
