This is a really good idea kaz (of eagle's) I think I may copy you both, as you say it gives you an idea of how you are improving, and I can certainly see an improvement even in this short space of time.
I know what you mean about the butterfly. It has a looseness that is attractive in itself and it is so easy to overwork things. Plus the question of "what do I do now to improve it?" when in your head it is "done". I guess you could always call it v2
A good chance to add extra sketches too, as you do challenges or if you get carried away sketching lol. Good luck
Just keep on painting. Your portraits do show improvement as they go. I think it would be worth working on that butterfly. That would look superb all tightened up. Keep it going.
