Kronos (reborn) topographic

[Harrg]

I spent many time with g.plates. Now I understand that here can be 2 t. plates, mb 3, not more,(how it said Charerg). I need back in tectonic and remade it, because I feel not that I understand my relief very good and it stoped me to make DEM.
1. I whant save my map size, mb make it ~5000-5000 or 7000-7000 km.
2. I whant save basic relief idea. Tanat mountains(big middle mountain chain). and basic view of coastline with corrections.
3. If I continue use 4000-4000 km and 2 t. plates, it meen that I need redraw north. I don`t belive that north plate have so small land. Mb islands? Or something conection like Kamchatka - Alaska? I think this is the better choise.
4. I don`t whant detailed enother continents, but i feel, that witout it I don`t understand how make Kronos.
5. My experement with tiles looks good like for me. Who find 2 dragons on map?)))) But I need redraw DEM, because it looks unrealistic.
6. Scale size. I need choose zoom. I whant see all houses, rivers, towers and ect Mb 500 m?
