Alright, I found this to be very cool, and I understand this is in alpha stage, so there are plenty of bugs. First thing, the box that is used for the inside of the C47 needs to be remade so that it fits the model better, and doesn't stick out and stuff. Also, reverse the door, so it's towards the rear of the plane, it makes more sense, and doesn't look funny when you fall through a wing.
Second, don't have the world boarders as a square, it's nasty looking, and it'll rape VIS once you do more to this map.
Add more detail to the ground, hills, something.
It makes sense to blow up a wall to get inside, but make it more obvious. Add like a gate to the base also, how the hell do the axis get in and out :D?
Get rid of the barrels you can move. I love to mess around with those in legoland, but it's too glitchy and doesn't fit well in the map. I can walk through doors, they don't open, should fix that. Add some models and stuff to the houses, and make them different. Some ladders look like they are floating. The ladder to the roof isn't needed, maybe scrap it. and the buildings look scaled too large in game, might just be me.
Last thing, I can see windows and ladders while I'm still above the sky, see if there's anything you can do to fix that.
