I like the explorer-girl a lot, it's a nice idea to put her in front of a map like that. There's some technical errors, but that'll probably solve itself with practice, my personal opinion is that it's better to know what to drawn than to know how to draw.
A technical thing you could improve on would be to stop using short, nervous lines instead of longer, flowing ones. There are two reasons for this; 1. It simply look so much better, and 2. It forces you to use your brain to draw. Drawing is after all a mental activity and the more you think about the lines you make, the better you will become at drawing.
