Hmm, well, I have wind coming from the north-west of the island usually. The island has the form of three circles, one top left (small), top right (huge) and middle bottom (medium). Of course, not exactly circles but you can make out the basic shape, though the top-left one runs out into a point at the top.
There are mountains along the north, north-western and eastern coast, as well as some small ones at the south-east. There are some streams coming down from the mountains due to melting ice and rain, which lead into small lakes. These lakes usually have a very long river that goes to one bigger lake, which is connected to the sea with several small rivers. There's a desert in the middle of the island, because there's already any rain there -- most of it is stopped by the mountains.
There are some gorges in the north-west, which have artificially created bridges and sloped used by humans and other species to travel safely across the canyon.
:P
By the way, I have a question about river deltas: is it possible, if a river branches, for those branches to not lead back to the sea or an other lake and instead lead up to a swamp? I read your swamp "tutorial" which made me come up with the question. Can a river branch lead to a swamp, or do swamps form around a river branch, and that river still leads to a lake/sea?
Nice world maps ya got there too. Interested in some additional practice? xP
