I have to agree, bit surprised there are only one...well, now two comments on this. It is very well done and you seem to have put a lot of time and effort into it. The rocks down below look great and the structure is very well done.
I'm surprised no one has commented on this yet! The ladder and wharf are nicely done, and I like the way you gave the impression of it being surrounded by a marsh. Looks like the pirates won't be going anywhere soon though, with that croc in the water! ;)
