That's a pretty cool five-minute map! Probably a bit silly but I like the craters - specifically how you used the line to define the inner edge but it's not a clean line - as they have a nice look that fits with the overall feel of a quick map, but not too perfect in relation to the rest.
Kind of curious, your spaceship has 4 beds, but only three chairs up front? I ask because it almost looks like a segmented craft that's designed to have the front as a sort of 'life boat' which can separate; however if that's the case, 4-beds, 3-chairs... someone's gonna have a bad day. Love the space suit!
