I'm currently working on a "Specialist and Promoted Units" paid asset pack to expand the Fantasy Battle Pack which will be my next big release. The initial release will have a promoted version of every unit in the original pack, and then there'll be free updates adding flying units, a ballista and a new cleric class. Depending on how that sells I like the idea of following it up with unique faction packs with themed units, a set of monsters, ships and airships etc.
Hi, I'm not taking commissions for the foreseeable future and as a rule I don't take commissions related to the asset packs as they frequently overlap or conflict with my own plans.
Regarding bigger tile / sprite sizes - it's something I've thought about but I don't have any plans for in the immediate future. I'll be focusing on expanding and updating the existing tile sets and sprites and creating accompanying asset packs.
Thank for letting me know. It's ashame but if you happen to change your mind later please shoot me a DM. Here is what I am building with your asset pack.
