It's the shapes of the furniture and floor tiles that gave it away. (Aqua has an extremely distinctive style that's immediately noticeable, especially when it's reproduced) While I can tell some of the window shapes are clearly custom, others seem to have been copied from Aqua as well. I'm not trying to sound rude or accusory or anything like that, which is why I contacted Aqua in the first place when I was looking for tiles; I'm not going to attack you or be mean about things, especially if there's always the possibility that the original artist is cool with you referencing their work like you did, or if they simply don't care that you did (I don't think there's a reason to be an ass unless a reason is given. =) ) Hopefully it doesn't take until the heat death of the known universe for them to get a hold of you either way, especially since, regardless, you've definitely got talent. ^.^
