Thanks for the replies ^_^
Fool: haha, true, and I did originally draw her normal hands, but I'm kind of attached to the hooves now... I think it makes her look a bit more interesting ^_^
Sharm: oh, now I gotcha! I'm fiddling with the aa right now, so I'll be sure to pay attention to what you pointed out.
Vellan: the fading foreground was one of my worries... I'll be changing around the background colours, I think to paler tones. A darker background (at least the one I tried) didn't work too well, the dark browns seemed to fade even more. As for the crowding issue, I see what you mean. I moved the top-right bird further out and I think it really helped with that.
I will post an update later today, thanks again ^_^
