Hi there MC. Well it looks pretty good to me. Unfortunately, I don't own Photoshop and so have never had the opportunity to try out this tutorial. So I don't know how to advise you on your questions. What you are doing is good though: that is, it's a good idea to try out several different tutorials/mapping styles so that (a) you gain knowledge of several different methods of mapmaking, and (b) this gives you the opportunity to develop your own unique style as well.
