Hello again arsheesh. I have some more questions:

I don't know what I did wrong, but I didn't notice any difference following the bump map stage. From what I have read it is supposed to be a big deal. Do you have any idea why? It doesn't look bad.

If I added the gradients and have then been fiddling with my rivers and lakes, is there a way to do the gradient over? Now that I have looked at it more I would rather it be changed; the colors don't sit right with me. I think you linked a tutorial about creating and editing gradients which I will read, but before I do, can I somehow remove your gradient?
