it’s really coming along, you’re getting a nice flow. i was making some similar wings last night and noticed that dynamesh was leaving holes in them if i made them to thin. i notice your blue butterfly’s have pretty thick wings - so are you having the same issues?
An evolutive 2KMESH (speedinamesh concept 
), if i can i show the evolution in dinamesh…a same base mesh for 4/5 versions diferents… few hours…
for holes, no problem, i did it in boolean operation in dinamesh (with key alt down + brush insert sphere)

Serie Of Evolutive System Mesh
At the bottom, you can see the first dinamesh base for create an another sculpt.
