I agree with this, especially if it is his custom textures that he made.
It is a nice map, do not get me wrong. And I get using someone else textures that are custom seems easy, but you are also trying to sell this map from what i've seen, and those textures Keo made for his other map, just doesn't seem right to me.
But not much I can say, gfx designers take other peoples pictures and sell them as login screens/loading screens/websites.
Either way, its a decent map other than that. The only thing I can suggest is to decorate a little around the edges, so that players cannot see just pure black around the edges of the town, would make it seem more 'realistic' in my opinion. =]
