I would say everything in the Sea of Flames tileset looks awesome, except for the tiles that replaced the castle ones which I still don't like. Those tiles do look a little better than before, but they don't really fit in and could still look a lot better. The textured background in 8-bit could've had a better palette, but it looks fine in 16-bit. But I have to say, the tileset does look a lot better in action. As for the Burning Cavern set, I liked that a lot as well, although the foreground that scrolled across the screen was a little irritating.
