Not a bad start A few comments: your coastlines needs a bit more of work to look more natural. Also the shields don't really blend very well with the map at the moment.I'd suggest to tone down/mute the colors abit and/or add a light texture similar to the one used on the map on them with a fitting blending mode to make it blend better. You use some projection and graticules here: your labels should be curved along paths according to those graticules. Staight labels don't really make sense fot now.Hope it helps.
