Mark and Tyler UT

The other day Mark made a livestream with Tyler playing Undertale ((finally)) and the whole time Mark tried to persuade Tyler to kill everybody in the game, so, I did this (?

Hope it looks good, I tried a chibi style, and I'm not used to :'v

Also, I didn't know what to do in the background, looks awful.

EDIT: I changed the drawing because it looked really bad, does it look good now?
EDIT2: I changed the file twice. No, it doesn't.
EDIT3: Tyler's left sleeve isn't shaded aaaaaaAAAAAHHHHHHHHHHH.
