the illustration style is too basic.
you've got the option of four colours, atleast use a little more to gain some visual interest.

your line weights are all too consistant which makes for a pretty flat and uniteresting piece.

and the guys face looks too 'charlie brown meets linus'-esque.

sorry no.

its pretty.....boring

Too simple

nah you need to spice it up a bit or make a punch line.

Yes! Another MS Paint submission... Takes me back to when I was 6 years old and learning how to use a computer...

Sorry, but I have to agree... pretty boring. I mean, it's cute on it's own, but it just doesn't compare to all the awesome designs being printed lately.

Personally, I wouldn't want everyone to stare directly at my boobs.

Wow, this was hated. Much more so than the pooting dog! I'm kind of surprised -- I still like it. Maybe a first-comment effect?
