i think this map is too simple. i wouldn't call it bad, but i'd like to see something more inspired from you. it's too bright everywhere making the lighting overall pretty mundane, though granted it is in space. the closest route from one flag to another (the teleport behind omega flag) is very boring and would get repetitive very quickly. it also leaves little reason to venture to the rest of the map in the CTF game mode, other than to pick up the rocket.
every hallway is the same, and while a good and unique layout that flows is a plus-side in a map you need to fill it with appropriate details and have it fit the strategy of the game modes. i'd start again from scratch or choose a different theme for a map, i can't say there was anything that excited me about this map at all and it would really take an overhaul to make it any better.
i think you have some good creations in you yet though, so don't give up
