Finally I was able to draw my two military characters together, Sigma (the one on the left) along with his "best friend" Alex (the one on the right), originally both were demons but I changed that and made them human (because I already had too many got damn).
They met in the war and well, they are friends since then, Alex secretly loves his friend Sigma while in the army, but does not want to tell him why he thinks Sigma is heterosexual, I hope you like it
