The Lorax: What have i done?

So 2 weeks ago i saw the lorax and absolutely loved itX3!! even though i never read dr seuss the lorax or had any idea as to what it was before i saw the movie it was still good!
My new fav. character the onceler and the LoraxXDDD
So anyways this picture shows the onceler realizing his misteak and being broken up about it because he soon realizes he will regret what he had done his whole entire life

please try to ignore my misteaks i just started using paint tool sai and im still practicing how to use it. thanks
