Alo Hoheim here. I'm a Freelance Artist.
So... this was a monthly challenge for the February 2020, from the Art Community of Trent Kaniuga.

Description Challenge:
" OVERWATCH SKIN DESIGN! The art of great skin design rests in creating a catchy theme that will make players drool over a character that they already know and love. This month we're going to show the internet who's boss and design skins for Overwatch characters! Choose any existing Overwatch character, and create a whole new look for them that fits their story, or the world of Overwatch. Bonus points for knowledge of a characters lore within the design. But nothing is off limits! Create a cyborg version of McGee, or a banana suit version of Winston. Hey... I don't judge. Flex your creative muscles and give us a turnaround with callouts for details all in the Overwatch character art style. Note - This is completely unofficial and despite Aquatic Moon's relationship with Blizzard and the Overwatch team, Blizzard has no involvement in this months challenge. This is purely for your own portfolio, and for a fun concept art challenge to develop skills. "
