So I got this commission (and other, related ones) on May 16th, 2017, and I have held off on uploading them since I have forgotten who I commissioned for these images. If you are the artist, please let me know, I would be glad to work with you again.
For ease of viewing, I added a white background behind the drawing, as, in the original form it was black and transparency.
And yes, I got permission from sketchy mouse to commission this character.
