Hi everyone. I'm looking for a little feedback on a work in progress.

Below is my first attempt at worldbuilding, with mountain ranges and highlands marked in red (and light blue for the underwater one). Before I attempt to draw detailed mountains and figure out the river systems and climates, I wanted to make sure these all make sense. I've labeled them with letters to make talking about them easier.

Does anything here look horribly out of place? Anywhere where you'd expect mountains where I have none? I imagine something isn't quite right, as I've been eyeballing (i.e. not figuring out) the plate tectonics. How do you all like the map in general?
