Haha, I've thought about a couple of those things. The front gate thing does bother me a little bit, I was thinking of adding some railings for it to follow.
As for the lift thing - I wasn't too worried about that right now because it's been left until last. However, I was thinking of implementing something along the lines that is in another of Lilly's concepts:
And lastly the door - originally I wasn't going to include it at all in case I didn't have time to finish the outside, so I wouldn't need to worry about seeing that area. I changed it and added it though because the image felt off in that area. I'll have to figure out some kind of suitable door for that area.
Thanks for the feedback man!
