The nebula side looks great! The basic starfield side is ok. The two main problems are that the map is too dark to draw on, so you'll need miniatures or tokens to represent hazards and other markings, and the hex grid is horribly aligned: overlapping hexes, grid lines that differ in thickness. The first problem could be fixed by using a light semi-transparent overlay over the whole map, maybe only on the starfield side, such that drawings become easy to see.
