Not downing me at all! I think I might've not paid to much attention when I put a white outline around the island. I totally forgot to AA that! I found the bulgy curve too, I'm gonna try to fix these small little things tonight. 

I really appreciate the feedback!

Much better than the previous on the island and everything. You still have a lot of jagged edges on the outline of the bigger mushroom top. The curve on the very left side seems very jagged, I'd suggest lengthening the outermost edge/like so it's more clear there's a transition from the top and bottom of the curve.

The colors for the mushroom are looking nicer. I'd still like to see some of the grey/darker lights drawn over into the spots closest to the light source. For example the spot farthest to the right could use a continuation of the curved shadow on the mushroom.

Last thing, the bottom curve of the underside of the mushroom is bulging a bit. From this perspective, (and from guestimating from the top curve of it) the curve would not dip down as much as it does. If you could move it higher (slightly) and make it a bit similar to the top curve, I think that would help set the perspective.

I hope this doesn't sound like I'm downing you! I guess I got a little excited, seeing how much you've improved so far. Hope this helps!
