Thanks ArchArad! I apreciate your comments. Since it's an unfinished model I'll follow suggestion and maybe I'll add some more redish foliage in the base when I paint the Orc rider which isn't painted yet so it'll be better colour balanced :)
Great paintjob. The brightness of the scales is balanced nicely be the toned down wing membranes. My only suggestion would be to steer away from so much yellow in the base foliage. It does tie in with the wyvern, but it also makes the whole piece rather monotone.
