Sorry, saw this a bit late. It's a nice start but the healer class icons don't have to have the same outer style as the creature type icons. Furthermore there's a lack of straightness when it comes to the lines and some questionable choices with the forest healer icon. For instance why did u choose 4 leafs when 3 would've fit a lot better with the light lines and ocean waves.
If you can make the lines straight and better fitting we could use it but currently it seems quite half-done.
I'm glad you saw my post, it's possible to do better, the objective of this first post about this was exactly that, to bring ideas, to help in the construction of these symbols, there was no way to bring one completely ready without receiving your appreciation.
