If pictures are posted, and feedback is wanted from these forums, you'll be getting lots of opinions from people who started loving this game a decade ago. That means that lots of us will be resistant to changes from retail to that are not obvious improvements, simply because it detracts from the nostalgia factor.
Whether the artist listens to any of the advice is their choice alone. You've said so yourself before, mjn, and that's fair and makes sense. I do mind when asset creators get bitter from negative responses and nitpick criticisms though, since it almost feels like they're implying "I want to hear feedback, but nothing that disagrees with what I already believe".
(Also, I vote we make the canopy grey instead of brown. The celebration pics thread did sort of make that part stick out more than I'd like)
