I've been busy since I got back from France (the Millau bridge is stunningly impressive, by the way), so I've only just got round to trying a bit more cloning.
The latest version is here
For Kraellin here's my personal critique: better, but still a way to go. I'm starting to understand the principles now of using successively less opaque "washes", but I need to work on the practice of it - blending edges into the surrounding area. This becomes (painfully) obvious looking at the clone layer
in isolation - the brush stroke are still too... "well defined" is the only way I can describe it.
Overall, I feel that it would pass muster for most purposes, but the perfectionist still says: "keep practicing".
