I think this is an excellent first attempt. You've mastered some important techniques very quickly and it shows. Contrast is important, but complicated. It is hard to be subtle and yet still make your map easily understood. The white text is a bit too dramatic and would probably "feel" better if it were taken down a few nothes. Another important detail is toning down your blacks. They aren't as visually startling but pure black would fade on an old map.

Rep to you for taking the time to learn so much before beginning and for producing a nice map.
