Hey, thanks for the feedback you guys! Made some changes and have now uploaded the most recent version (EDIT: accidentally posted the wrong link at first, and so the image didn't show up. Whoops, should have previewed it first...
):
(Apologies for this taking so long, summer is sadly a time of year I typically don't have much free time, oddly enough) This version makes the gaps between the bumps on the trunks wider and smoothed them out like eishiya recommended, though I'm not quite sure if it should be smoothed out further (though the changes already made do make it look nicer IMHO). Also added a few leaves here and there to the closest layer of the background and made the further layers gradually fade into the background. I'm also still debating whether I should make some of the stalks bend slightly or not.
But yeah, thanks a lot for the feedback, I found it helpful, and once again, criticism is greatly appreciated!
