I watched the butterfly video and thought to give it a try
the first attempt was not good, lots of cracking issues. But I do like the wing shape better than the second attempt, probably because I made these wings directly on the body and could see better how to get the proportions I desired.
the next one was better, less cracking. I made the wings separate and attached later. Not so keen on the wing shape and it was harder to match them as I couldn't use the first one for reference (my hot plate is black). Next time I will sketch the desired shape life size and from a top down perspective as a guide to make them the same.
