Older piece I dug out year or two ago and pushed it to final state :)
The sketch itself took me couple hours, don't know exact time- I just started figuring out things and it landed in my drawer for year or so. After I dug it out, I spent around 10-12 hours on painting. Initially it was more scifi'y, but I took my time exploring various ideas that led me to that result. I think exploration was the main time-consumer here :)
Hope you enjoy!
