Mandala, design #146 makes a chance if you can realise the following corrections:
1. texblock like #23
2. blue part in brushed metal
3. no chimneys
4. one big window instead of 4, also in the orange part
5. make the window 3d-feel (can't see the thickness of the ring)
6. make the sunshine/shadow more logic (outside-under = dark, inside-above is light etc.)
If there is not enough time, just make only the logo.
