WIP: Elesz Kiervicz sketch to vector

Found some old sketches that never got fully completed. They were meant to be stained glass windows in a restaurant, but I can not find any record of them ever being made. I can't even find anything on the artist who did the sketches. So I decided to honor the artist by taking it to vector. This is a close up of the illustration so far. Attached is a screenshot of the full sketch.
