World map of Cindaelus. Criticism wanted.

[Sursion]

Hello all,

As the title says, I've created a new world map of a world I call Cindaelus. It's very basic (made in paint) due to my horrible artistry skills. However, now that I've got the basic outline of the land, I need to move on to the next step: making it as realistic as possible. Where would the deserts go? Which areas are temperate, which are rainforest? What are the plate tectonics like (I have a vague idea, but I'm interested to see if it's plausible)? Any advice you folks could give me would be very much appreciated. When I make things, they always have to be as realistic as possible. If something doesn't have a good explanation behind it, it will drive me mad forever.

Criticism on the map itself would be helpful aswell. Do the landmasses look proper? Are they too smooth? Not enough of this or that?

Thanks to all.
