WIP - A serious attempt at mapping a fantasy world

[Silversweeper]

After spending several years lurking on the forums and working on different versions of a world map for a fantasy world that I never finished, I have decided that it is time to make a proper attempt instead of several half-hearted ones. This means starting with tectonics and a *very* rough land/sea map.

The map is roughly equirectangular, though I have cheated a bit at the poles (the map stretches from about 85° N to 85° S). The planet in question is roughly Earth-sized and I have decided to assume that it has more or less the same axial tilt, planetary albedo, orbital period, a same size moon, etc.

One of the attachments shows just the land/sea outline. Note that this is extremely rough at the moment and that most of the smaller islands will either be removed, be split into multiple islands, or become much smaller before the map is done.

Another attachment shows a very rough mountain range sketch. The green areas are where I *really* want mountains, while the yellow ones are areas where smaller ranges or no ranges will work for the world I am envisioning.

The third attachment shows a very rough tectonic map, which I have attempted to base on where the important mountain ranges are. The arrows indicate how I think the plates should move, based on my limited understanding of tectonics and where I drew the mountain ranges.

Things I would like feedback on:
- Does the tectonics make sense?
- Do the green mountain ranges make sense, based on the tectonics?
- Which of the yellow mountain ranges make sense?

Things I don't want feedback on at the moment:
- The shape of the coastlines, unless it is related to the tectonics.
