Not a bad first map! (although you might want to get more familiar with the forum's gategories and subforums - right now your map is on the Tutorials/How-To section, while a more appropriate location would be either Finished Maps, or the Regional/World Mapping WIP section, if you are planning to work on it further)

You have some interesting continent shapes going on, and I like the overall layout of the lands, rhumblines and other elements. The coastlines and rivers are looking a bit rough still (are you using a mouse or a tablet?), but that is something that will get better with practice. You are certainly on the right track, keep at it!
