That looks great!
Right now there isn't a real plan to make similar diagonal patterns for other autotiles, specifically because there's some engines where the autotile doesn't really allow it (in RPGMaker notably, they force them to be very square if you want them to be animated), but that's a good idea, and I'll keep that in mind for potential future patreon releases or expansions.
Thanks

Thank you for feedback, and hope to see some updates on Patreon! I can also share source draft pngs/aseprite files I was experimenting on, if needed - just let me know.
Regarding incompatibility with RPGMaker - that's really strange, because as far as I've checked their documentation its autotiling is using pretty simple "corner sets", and first option that I posted should be perfectly compatible with it - just need to rearrange tiles into pattern it expects. Second option is a more tricky, yes - in Tiled terms (which I'm using to build map for custom engine) it is an "edge set", and probably is not compatible with RPGMaker.
