Thank you again for pointing at the i dots. By myself I would never have noticed them. Indeed now it looks at bit strange.
Another point on my list then!
I'm glad for any tip I can get, since I have no 'teacher'. Please continue to point at things. This helps a lot, to leave my narrowminded view. I would like to invite you to be picky, as this will help the most. I want to improve, not to be cherished when there is no reason for it.
As for the alphabet, this is from 'David Harris, Das große Handbuch der Kalligraphie, 100 Alphabete mit genauen Anleitungen, p. 118.' I made some adjustments by myself when I was not particularly convinced of the form.
I'm not sure about Copyright and such things, so by now I can't post a picture of that alphabet, since I would then publish a page from the book. I hope you understand me being worried about this.
