Love your work.  The "forest" and "playground" tilesets from "Open Gunner" are perfect for a fantasy setting and I can easily re-color the "background" tiles to make them more appropriate for these sprites.

Any chance of expanding this pack as well?  Really only need a few more mobs -- orc boss and brigands (or maybe trolls) and you'll have the makings of an "Open RPG/Platformer" art pack.
