Not really sure if you're going to be able to see the image but I created a quick sketch of the doors for fun.
Door one - looks as though it is a portal to another galaxy. It seems to have some dark ominous Aura coming from it. But you are stuck mesmerized by its illusion reaching for the door as it calls you in.
Door two - you seem to be staring through what almost looks like a window. But it's a door! There seems to be a small bit of water filling out from the bottom but you are now locked and the only room that's left.
Door three - You stumble across a red glowing door on an outer gate hidden behind some vegetation and overgrowth. You wander onto an abandoned land with many signs along the way saying... Restricted area, no trespassing, radioactive and stay out!
