My reasons for that post:
1) Your nick is Luke, not Lucas, I didn't know you had multiple accounts
2) Even if you are also Lucas, the red brick tiles were made by someone else, not you
3) People will not be editing and helping you out if they realise you might just take their edits and pass it off as your own work
I'd drop the red brick tiles as they don't really fit in with the rest of your tiles anyway, they're obviously another style and quality.
The bookcases and windows are very very dark and hard to read, try to lighten everything up a little. Also, since this is topdown view is used, the windows would reflect the floor, not the sky. Windows only reflect the sky if you're looking upwards, not downwards.
I'd edit to show you what I mean, but... yeah
