As always, appreciate your kind words Erik! And to be honest, I still can't wrap my head around your space anomalies images which are all amazing looking and far better than what I can think of! :)
Hello! Thank you so much for the kind words!
And to answer your question, the time it takes to create a piece like this is very different depending on the complexity. But normally, from sketches to final work it can take 2-3 workdays.
