Nice!!! I love seeing your work. Here's my current work in progress on it. It's just a subtle refining. I've changed about 20% of the tiles, but most are only by a pixel or two. There's a few easy tiles to re-purpose from the bottom. The benches can easily be drawn with one less tile and look almost identical, and the semicircle area on the ice can be simplified to use more flipped tiles, to free up another tile or two. IIRC, the boards also have at least one tile that is easy to steal.
I will share my Photoshop files for the tile maps etc, soon, in case they are helpful for anyone. Should I share them here, or start a "How to edit the Sideboards / Pause Screen" thread?
