Hi Moki!
Welcome to the community!
My advise would be, there are some maps that one can chase perfection on, but there needs to be whole slew of ones that are trial and error along the way. If I had stayed on one map I would never have built my world as I far as I have.
For instance, the world map can just start out as rough line art just to get the ball rolling. Leave it and pick somewhere on that roughly drawn continent to further expand, maybe this one would have a second line art pass, or some color. And then when you feel there is potential on an area you can then decide to do a deep dive map that you meticulously detail over months bit by bit.
But in the end, having rough drafts help sharpen other types of mapmaking skills. For instance we just had make a map in 5 hours challenge. Quite tricky. But it teaches AMAZING lessons, since you learn to prioritize different things when you have limited time. Id highly suggest you give the 5 hour map challenge a shot. You will learn a lot.
I'm excited to see your journey! And be sure to post your maps!
Cheers,
Omri
