Well if you can't think of anything that you could do better on that specific piece than you can always move on to the next one. Afterall it's not like there was much to fix anymore.

Personally I'm waiting for a piece that really shows where you have improved such as multiple characters. Tara is just simply saying "never settle for less". I would say the same thing so if you ever have a chance to redraw a specific drawing and have the skill to make it look significantly better, then go for it.

Now I did mention issues that I had with it. Specifically line variation and I also pointed out that based on this particular drawing I'm not able to judge how they know anatomy so not the best example as the characters are in specific positions where I can't see it. But it is well drawn either way.

Still you're over explaining just for the sake of it.
