Yeah I feel that man. It's really hard to keep working on it after the competition ends.
I really like the way you used shadows to detail empty floor space in some of those screenshots. Thats the kind of thing that gets me excited about mapping. Really good job man! I'd encourage you to keep it published to show how far you've come and let people walk around it, but I get that might put pressure on you to polish it. Good luck with your next project! Looking forward to seeing your entry when the next competition rolls around.
