Larsaan is right. A good portion of these are Wakfu pictures, not really D&D-related: 15-18, 22, 23, and 42-54 can definitely be sourced back to the French MMO-turned-cartoon.
And for Dagon, the artist has his signature in the bottom left: "KennoArkkan"... ...unfortunately, you won't find it on any of their socials, since everything he posts is 50% webcomic and 40% furry art.
