Wonderful Water

Hello!
I performed these works for the competition. The theme of Crystal Canvas 2020 is “WATER”.
The name of my project is "Wonderful Water."
It was interesting to come up with the plot of the game and the images of the characters for it.
A little about the plot:
The game takes place in a world where it is extremely difficult to get clean water.
The surface of the earth is covered with a thick ice-like crust, under which the waters of a toxic ocean flow. The land is an archipelago of small and large islands.
People here have to survive in difficult conditions. A lot of them become ill or mutate when exposed to toxic substances. So they dug deep wells to reach rare underground lakes with clean water. They also learned how to extract water from flora and fauna of the islands.
Many people become ill or mutate when exposed to toxic substances.
Our hero is a young boy Tilly, who lives in a small settlement.
One spring, people in his village began to rapidly fall ill, many died and the parents of our hero too.
He was left an orphan with a sick little sister in his arms.
He heard from a swinging merchant a legend about wonderful water capable of curing any disease, but it is very difficult to get it.
Only a witch from the northern islands knows the way to her.
Tilly embarks on a dangerous journey for wonderful water to heal his sister.
Many dangers will lie in wait for our young hero on his way.
Get acquainted with interesting people and amazing creatures.
But time is running out, to overcome everything in achieving the goal and be in time, that's what you need!

The concepts I've created represent several story characters that Tilly will meet on the way.
I used Photoshop and Zbrush.
Thank you for attention)
