That is a great tutorial on hand drawn maps! I wish I would have had the access to material like that when I first started (or at least the knowledge of where to look!). My own pieces are far from masterwork It has been a long journey, that is for certain. I would say that, at this stage, I am...satisfied. Here are a few links to some of my more recent map making endeavours.
Quill & Ink practise
Wheel of Time map, slightly older and of a different medium (pencil instead of ink)
Progression of map making, a brief look at where I started and how I got to where I am.

I hope this was of some use to you, and best of luck with your first map! There will always be a special place for mine, and I have redrawn it around 6 times now!
All the best,
