Ypu know, all of your dragon pictures put into one, would make an excellent dragon guide book. You could make a lot of money from it too! I've seen TONS of copies of dragon guides and references in book fairs everywhere!
Oooh, beautiful wing design. Wyvrns were a dragon type in this dragon species book I read if I'm not mistaken >.< Beautiful creatures, but anywho- Bravo! You never fail to capture their unique details.
Just a wee technical tip-come-nitpick... That very cute dragon would have no chance of camouflage with those colours around the coasts of Australia. Inland, certainly... but not where you've indicated habitat. That'd have to be more green/blue/yellow. Just sayin'. Loving the colours though - very Australia. And his crest reminds me of a frilled-neck lizard.
