I promise you, I did not rip off your character. It's just that I drew myself as a character wearing my favourite shirt, which is a pink and black striped jersey. I've had this jersey for a long time and I have drawn myself with this shit multiple times.
I will improve in drawing bodies, I'm not used to it yet, so I took a sample body and drew that. It's kind of fun drawing in Photoshop. Pencil and paper are my usual choice.
