Three works done recently based on the aesthetics of the 1980s. Two of these are available as apparel on my DESIGNBYHUMANS store: https://www.designbyhumans.com/shop/SOMNIVAGRIOUS/
The South Dakota poster will not be available as it was a gift.
The tiger and buffalo pieces were both done entirely in Clip Studio Paint but the tentacle one (which is a little older) was done in Photoshop CS5.
