Now it becomes to look like your landmasses...

Final thoughts... it explains quite well the central area of the map - I just couldn't reconcile "my" plate (7) with that sea you had in the same area. Other than that, I hope you like it.
I did this in a couple of hours today, it shows the kind of information you can have for topography. It was sloppy as everything was done with little consideration to how things warp as you move them around in an equiretangular projection. It's always much easier when you don't have a "target" coastline to fit things into.
