Fineliner line art with white and gold

I tried something new again. I made some line drawings with fineliners on dark drawing board. Then I added highlights with a white artist watercolor pencil and finally highlighted with a golden Edding Paint marker. I'm quite happy with the results! The scans don't really reflect the effects. Therefore, please take a look at the short videos, where this is more recognizable.

What do you think of the pictures and the approach? Do you have any other ideas or suggestions?

You can purchase the drawings in my shop as originals (on request also as art prints, posters, etc.):
