you seem to be on a roll with creating ships! say, where do you get the ship art? do you make it yourself, or pull from the internet? if it's from the internet then you should definitely credit whoever made it.
now about the ship. okay yeah starting with two advanced flak does seem rather frightening. there seems to be an extra power capacity for weapons in that case (2 adv flak's are 2 power total, 3 power in weapons). The fact that there are 6 slots is fine though, as I've seen ships with more than that.
and also, there is a pretty big glow offender in the engines room, what with it being on the floor instead of on the console. the room below engines (the 1x1 room) isn't connected to the rest of the ship. you could either connect it to the rest of the ship or make the engines room a 3x1 (or is it a 1x3??). to be honest you might not even need that airlock, as that could be part of the ship's challenges. it's up to you, really.
Did someone say Foxhound??
