I don't have much of anything adult-rated, and if I did have such, I won't make any of it public.
It's just the issue on which place is best to post some of my work. I know some artists have their work on both sites.
Back in my paper soldiers artwork, I'm focusing on the basic templates of various stances of my soldiers, and I'm fine-tuning the furries' heads for different species and proper headgear. So far, the furries I'm working on are canines, but felines and other species will come later. The worst time for me to come will be when I have to make troodon-like soldiers and ALL of their weapons, gear, uniforms, vehicles, and aircraft (yes, they'll fly planes too).
Now to answer the question of "what you talking 'bout, Kenji?" I'm doing all my paper soldiers artwork around a group of fictional nations that I made up. The country I'm doing now is the Kingdom of Estelbach, a nation primarily of humans, but the past few hundred years have seen an increase of furry immigrants and citizens, even starting to fill the ranks of the Royal Armed Forces, but the majority in the Royal Foreign Legion, but not limited to other branches. Soon, my world will expand with the Narxcus Empire, an authoritarian regime of humans who treat furries opposite of Estelbach (almost like Nazi Germany), then Viriam Axtilae, a loose coalition of dino tribes (similar to Afghanistan), Rokugon, a Japanese-style nation of the extinct Hokkaido and Honshu wolves, and San Cloe, another human-run country.
If that's a lot of work, this is just the modern-era work. Wait until I work on them and others in the 1940's and 2100!
