Yeah, I wasn't sure about what size it sould be, will fix it, thanks.
And not yet sure about the colors of the buildings, or if I need to add something else to the building or just keep it like that.
BTW, Do I need to save each building separately and the background separately? or how does it work? is there other sizes I need to know except the BG size? or what format of the picture.
I'll try to install it on VCMI when I finish it and add all 16 buildings and update here
And thanks a lot to all for the feedback.
