Hey! Hurray, another tectonic geek.
All in all, this is a good start. The tectonic model seems logical to me. I'm not quite sure where Skardhyr is heading. If he is moving towards Quruma, then you should reconsider the types of the border. Somewhere there will be a fault. My main comment concerns the coastline, it does not correspond to tectonics. You expect to see similar landforms around continents that once collided and then disintegrated. Like the west coast of Africa and the east coast of South America for example. Island arcs or mountains like the Andes are also expected to be seen along the subduction line, where subduction goes under the continental crust.
Best of all, in terms of tectonics, you got the east coast of Osmor, where you were inspired by the east coast of Eurasia.

Thanks Harrg, yes I must admit I love tectonics! Regarding Osmor, I was initially wanting a 'Sakhalin' style island then before I knew it I had Kamchatka as well! Other shapes I borrowed are Baffin Island (the main landmass in Fjordhaerne) and Sognefjord (Norway), the main gulf on the west coast of Skardhyr.

Skardhyr was meant to be heading towards Qaruma and Osmor rifting from it, but looks like I need to rework that. So regarding the coastlines, is there any in particular or do you mean all of them in general?
