STEP 2: The Inks
Usually I don't really like this step, because it takes away some of the 'flow' of the initial sketch. But to make a somewhat representable map, it's necessary. There are two methods I use: either I clean up my sketch or I put the opacity lower and draw on a new layer.
In this case I used the second option. I've uploaded the sketch+inks and only the ink version. I will draw the rivers when we move onto the colouring. My mountains usually have two elements: the outlines and the shading, as you can see.
I don't have much to say. Make sure you work big, so you can be a bit sloppy and don't have to worry about every single pixel. It doesn't need to be perfect, especially if it doesn't add anything when zoomed out.
I've also uploaded a 100% zoom shot from the inked version. You see, it's rather sloppy, while on the resized version these little variations go pretty much unnoticed. If you'd want to post a high resolution file somewhere, then I'd be a little neater, but this time not so
My point is: make a nice line art, but don't spend your time on details that don't matter that much
Next: 'flat' colours, preparing to paint and possibly textures
I'll post that later on, I think, I want to paint it a bit more before posting my progress again.
