There are two things I really like and I can't draw very often: Kotetsu and a huge butt trapped in a situation.
I had the sketch for this since april, I went back a lot of times but I just couldn't... until last night when I decided I wasn't going to left him unfinished in 2019, and so he went from a half body sketch to a finished full body~
2020 is around the corner, if you have anything left to do before the year ends, be sure to do it, it's your last chance!
(I decided to make this post public because I personally want to share it with the world before the year ends)
