It was very cool to participate in a challenge, many ideas come to mind and this even helps you to produce new projects and the like, the sea bottom theme or "beneath the waves" was great!
You can follow my process in my challenge link: https://www.artstation.com/contests/beneath-the-waves/challenges/32/submissions/24409
I had as main inspiration the corals and seais of the sea, it was very cool and challenging to look for references, it seemed all stranger and "random" at the same time lol
but I think I managed to get an interesting result XD
hope u guys like it !
