well pixelled even if i can't stand that show. nice work.
@Sneep - nope, Spongebob is a rectangle (cuboid) and his face is in proportion to how he normally looks, you can find pics of him in Google images. But thank you for your comments :)
He looks too much like a rectangle. Isn't he supposed to be an oval?

Hm.... the face is way too big. Excellent details and shading.
Another spiffy piece--I always enjoy the brightness and fun of your palettes :)
Great work! I'm particularly impressed by the AA. Smooth without losing that pixelly crispness. :)
@Zetabot - I originally had the arms in that particular position as he was meant to have lots of bubbles in a semi-circle over his head spelling out 'Happy Birthday'. I will either add those bubbles or correct the arms, whichever looks better.
@skamocore - The background was an addition so he wasn't stuck on plain white. I will remove the high contrast and improve the background :)
Thank you so much for your comments and critique 
Not so keen on the background, but Spongebob is fantastic. Perhaps less contrast in dithery parts of the bg.
Oh man this is beautiful. I love the eyes. Full marks on this one
Just one nitpick I think would pull this together a little more, his arms should be a bit higher. They almost are to the top of his head and I think that is what is throwing this off for me. Fantastic piece though :)
Hahahaha, very cute! And a nice shading for a spongebob :P
This is the best thing I've ever seen in my whole life.
