Bad Time To Be Lost

_{Mature content for blood, just in case!}
Late art trade half for of their character Serr! Finally got to draw three-tailed character oh god  and his wings were pretty interesting! 
I did four sketches for the half (in every each of them he was floating in air, in two of them hunting/eating/whatevar). ;-; at least one of them worked well. 

Please forgive me, I have no idea about anatomy of canine butts or hind legs!
