The style of this is excellent. I'm reminded of claymation in that it's simultaneously very fake (not in a bad sense, just in a liquid representation of reality sort of way), and very real at the same time. I find this quite impressive.
Yeah, good stuff. It reminds me a lot of that cottage that used to be on Moonbeam's journal.
But zac is indeed correct in saying this isn't strictly Pixel Art, and ^ShoneGold will vouch for that. Creations should be made with pixel brushes only. A limited color palette should be used and transparency of any kind is not allowed either. I'd probably say this should go into Miscellaneous Digital Art since the other categories don't really fit.
