I think my scales are going to blend across the seams in the legs really well, but WOW, I can't even imagine doing the scales on the entire Dewback after just this little bit. I know they aren't perfect, but, they should be enough to trick the eye into not seeing them at all. Aves' Apoxie sculpt and a couple metal sculpting tools, then brushed with water to smooth everything out.
