Science Fiction tileset

Since last December I´m working on a Science Fiction tileset to use with RPGMaker XP. Also I offer the tileset to a scripter called game_guy to use it as exlusive in his Gregor Project (a 2D rpg engine), So it will be Gregor Project exclusive if author of the engine want it, in another case it will be free. This is a first screenshot of a map made with the tileset:
