It's like an underground base...
You've snuck into your main enemy's underground basement is the only thing you are greeted by. No guards. The lighting is dim. It's just you, a hallway towards your foe, and security systems all around you. It's now or never.
I'm sorry, whenever I hear original pieces, I picture something. It could be stupid, it could be awesome, it could be in the middle. For something new to you, you did an excellent job. I don't really see much of anything to improve on!... but that's just me!
Have yourself a 5/5 and a 10/10 as I download it.
