Awww shiz! Nice update on the first post. The helipad map looks a bit too symmetrical thou. And your gate needs more shadowing. Good job!
The new tiles are good, only needing a slight improvement. Also I recommend you to save the pictures in the first page as .PNG so they don't look blurry and more people gets attracted to your hack.
As soon as I saw this thread, I had to stop by. I can't wait to see more of this as work gets done. I just went to re-watch it this past weekend too. XD
