This map OOZES personality. It's unlike any other map I've seen (except for all those floating castles.. But they're not curvy!).
The map is an eclectic mix of architecture of varying shape. It's all well done. However, it did feel a little random.. and loosely connected. There was no unifying architecture present for me; like a pillar that is the same shape in varying parts to tie it all together. The random floating things (sorry Jon) further the randomness of it as they are not uniform either. You could remedy this by re-arranging them. Identical ones are right beside each other now, but they'd be better if they were split, one on either side. Hard to explain..
Anyways 4/5. As far as layout goes it looks solid but the aesthetic is a little off.
