I think that with CC you export to jpg or something like that so export it a little bit larger. The mountains seem to be placed logically enough and except for the rivers all it needs is some towns, roads, and labels. The more you play and learn the better it will be but that always takes time so don't worry about putting something out that you feel is inferior...we all start that way. For some real inspiration in what CC can do take a look at the stuff Bohunk does...he used CC almost exclusively for a long time (but recently incorporates Photoshop Elements) but you'd never know his antique maps were all CC.
