If I were to be really picky on the mushrooms I'd suggest that the ground based mushrooms and the bracket-type mushrooms should be more different in their colour schemes. Not that I'd ever be picky
I don't think I've ever sketched the Egrun yet. Don't expect them to simply be large smurf-style mushrooms though. I'm more likely to draw inspiration from some of the various weird seedpod type things that you find in florists. I've got some cool bits that I've found at various times that I'd like to play with at some point.
