Distracted a bit from the relief and tectonics and decided to have some fun with different palettes. This is useful when working with a heightmap, because identifies mistakes and allows a different look at old things.

First animation form gplates
As you can see, I understand well the history of the southern continent. It's simple. But I still have no idea how the northern one came about. I still don't like the collision model. I feel like I still have a lot of time to spend exploring the northern and western borders.
Some idea or sujections?
P.S. I seem to have a definite animation and bump mismatch. Probably, the southern continent should at some point begin to move stronger to the northeast in order to get the kind of orogeny that is now. It seems I started to see a number of inconsistencies. Why did such massive orogeny arise essentially from oceanic subduction in the east? And not in the west, where is the continental convergence?
Why is the coast of the Middle Sea so far from the mountains in the subduction zone? Sediment? From the side of the subduction zone?
The more I think about it, the more I want to say stop. Best the enemy of the good. But these thoughts scrape my brains.

I would say most of those problems have easy solutions, here are some ideas:
1) The Western & Eastern Tanat mountains
- Change the Eastern portion into an island arc that has collided with the southern continent as part of the process (similar to New Guinea). That way you can have the continent-continent convergence (and possibly subduction as well, on the northern boundary).
- The relatively small size of the Western mountains can be explained as well. Perhaps here there has been mostly subduction of oceanic crust, and continent-continent contact has begun only recently? I feel the plate movements themselves support this idea, as clearly the eastern part of the southern continent moves at a higher velocity (hence more crustal shortening must have occurred in the eastern regions to accommodate that movement).
2) The Middle Sea
- Again, the "ocean arc collision" explanation would go a long way to explain the Eastern Tanat mountains, they could be a separate plate, with a transform boundary between the E. Tanat and the northern continent (a situation similar to the Sea of Marmara).
- Though maybe the seaway from the Middle Sea to the ocean could be a little bit more open
Thanks Charerg! These are very helpful tips indeed.
I tried to sketch this out. Did I understand your idea correctly?
It seems I have caught your general idea, now I need to temporarily distract myself from the existing relief, tk. it is rather confusing. And pay attention to pure tectonics. Phew this is a really tricky region considering how much is going on here.
Yes, that is pretty much what I had in mind.
Fast sketch of new conitinent Albara.

This is great. What software are you using to create these maps?
Hello Hieronymus_Blaze! Thank you!Originally Posted by Hieronymus_Blaze
I use photohop, wilbur and QGIS
All my maps based on height map.
You're expanding your world, I see.
