That is a cool and clean map and should be useful to a game session.

The background texture is a little odd. Theres a lot of repeating patterns in it but its not all repeating. Its like you filled it with a repeating one and then pasted down lots of patches of rotated texture.

Heres a few tips there. You can get that texture and make a big square image of it at say 1000x1000. Get the same texture, scale it up with a nice bicubic stretch to about 130% in each dir or say 1300x1300 and get another at say 1500x1500. Now crop the two new ones to 1000x1000 again so that you have the same repeating pattern but at 3 slightly different scales. Now blend all three together and then you will have one 1000x1000 image with no repeating pattern in it.

If you then want to make that seamless then I wrote a tut about that too. Search for "seamless textures". Then flood fill with that and it will put down unlimited non repeating textures.

Its easier than it sounds. It also works better if you scale by prime numbers like 1.13 or 1.29 from the original. Actually, maybe RobA will add that into the seamless tiling script so that we have seamless non repeating textures...
