Use this. Btw... textures? What?
As I have now inspected your map, I may critique it critically :|
You could have much better textures, and the texture you used is extremely bland and looks to be random pixels on the ground. The map needs more character - add in unique aspects to it like traveling through a lake (slowing you down) and other things. Lastly I would suggest adding a small wall of fog, doesn't have to be a lot, just enough to hide the disgusting map edge thing going on there.
I found the map very dull... I know it's a desert, but you still could have gone further.
I may make a quick desert map in a sec to show you what I mean.
