There are a lot of great artists here on the Steem. @theonlyway is open for commissions - but hasn't been active for over a year, as my check revealed... @tezzmax has a cool style. A painting by @stef1 would certainly be a perfect fit - she implements the Steemit logo in many of her oil and acrylic paintings anyway and is an institution on the platform herself! Otherwise, we have a graphic designer in our circle of friends who could certainly realise such an idea well, but has no connection to Steem.
