It's allright, while I was working with your grafphics the last 2 weeks I figured some very nice ways to use GIMP to create about any terrain Animation Sprite as long as I only need to move / edit existing elements.
Your graphics are actually the reason for a whole UI Rework because your graphics were looking better for this type of game than my UI :-D
Not sure if you are into Turn-based RTS but I would like to drop you a copy if I ever going to release my project. You can also gift this copy to anyone, if you are not interested.
