I think the coloring got progressively better. The lighting on the last one might not seem as striking as the second one, but that's because it's more "ordinary," not because it was poorly excuted IMO.
I wish I'd done a better job drawing the dress in the last picture; it doesn't really look like it's being blown around by the wind. confused Oh well, hopefully I'll do better next time.
BTW, if you missed it, there was an art plug in the last entry too.
