Rebuilding an continent and a world - Feedback Please.

[joaodafi]

Already some time, I've been working on a personal project of world-building, beginning of a new year, I decided to redo from scratch this world in question.
I intend to use this world mainly for RPG campaigns ... and other things.

So, here's everything so far.

World Map outline, obviously is not finalized, it still has many islands and details to be added.


But it's okay to not be finalized yet, because the only area that I will use for now, is the north-central area.
Outline this area:


And here is the map of Height, yet simplified.

Black - Sea Level
Gray 20%.......0 up to 500 meters.
Gray 40%......500 to 1000 meters.
Gray 60%.....1000 to 1500 meters.
Gray 80%.....1500 to 2000 meters.
White...............Over 2000 meters.
Blue lines..........................rivers.

I intend to start designing the climate map.
well, I am bringing images here to know What would you have to say about what has been done so far. Basically tell me your opinion.
