Wow what a fantastic worldbuilding concept idea! Newly settled planets have always been an idea I've been fascinated with. Do you have any plans to sketch out the geography of the planet as a whole, or will you be focusing on this regional map? Though be warned, trying to put together a coherent planetary map is a dangerous rabbithole to go down, especially if you're focused on geography and climates...

I rather like your map style, though I think you made the right decision in transferring to doing it digitally- so much easier to undo mistakes! And with some practice you can really go back to the "hand-drawn" feel even when you're using Photoshop or Gimp.

I won't comment too much on the map itself for now as you'll be redrawing it, but just a note on the place names- not all place names translate well literally from one language to another. For instance, there's a city in Bolivia called Santa Cruz de la Sierra, which translates literally to "Holy Cross of the Hills"- a rather awkward name in English. Similarly, as a Spanish speaker, "Valle Ventoso" sounds a little... off, for reasons I can't explain. Like it's a name I'd maybe use for a suburban housing project, but not a village. On the other hand, "Vallegrande" (Big Valley) is a common place name in Spanish-speaking areas, if you want to stick with the same pattern. Oh, and it should be "Rocas Amarillas"

Overall great work! I'm excited to see where this goes.
