for the river area, try to make it out of more blocks, the more uneven it is, the more realistic it is...the pyramids look plain wierd to me :/ also, use diff textures for the underwater part of the river, make the river crooked for a more realistic effect. use the "triangle" technique, if ya dont know what that is, ask an experienced mapper, im too fecking lazy to type it now because i have a crapload of French hw and math so i dont really feel liek typing all the crap that im typing right now so it is really spam that i am typing right now and therefore wasting time that i should not be wasting and instead be wasting it on ESF/HW when i have no toher time left to waste on stuff like spam which i am typing right now and now i am going to stop because my hand is going numb because i am typing at a really fast rate and my hands are going blue because i took a few keyboarding classes in middle so now i can type fast, can you not see that, well if you can, ok i love you bub bye!!!
