Two point perspective practice

This is my small project to practice the two point perspective that i haven't done for a long time right now. It is good to go back to the basics from time to time.
I used traditional medium only, first created the pencil sketch. The two vanishing points were outside of the frame so I had to draw a basic grid and put it under the sketch paper.
(I'm planning to draw over this sketch with digital tools for practice later on)
After I used the lightbox to draw over the sketch with ink:
Materials used: mapping and G nib, N&W indian ink and some brushpen for the very dark tones.
It is a bit of 'old school' D&D atmosphere again, I loved to support my campaigns with some visual elements. :-)
