Trying to give constructive criticism on this is effectively impossible. It's like posting a crayon-drawn stick figure, and when people say it's pretty lame for a thirty-year-old's artistic attempt saying "Well why don't you give me constructive criticism to help me improve?!" There's so little to work with the only criticism even possible would be "Learn to art."
Seriously, the only thing I can even possibly say is try to watch some better comedy other than the shitty youtube bullshit and Ren & Stimpy knockoffs that this is clearly based on, and try to actually comprehend why it's funny. Things like playing with expectations, timing, and personality interplay.
So there, you want some constructive criticism, that's about as close as is possible with this. But I think we know you don't actually want criticism of any sort other than as some sort of validation for managing to "troll" people.
Or you can continue to flail around and we can continue to play Kick The Autistic, Ray-chan.
