Hey, I just want to apologize, I tried voting happy face on your picture, and accidentally clicked the other, just posting to say I really like this picture.
Spongebob is a nerd though. Your interpretation of Spongebob only shows him by clothes. He needs a nerdier expression, his features look a little too soft. I really don't see a human form of Spongebob in this picture. It looks like humans dressed UP in a Spongebob Squarepants theme. I don't even like the show, and no doubt you know how to draw well, in this particular field (manga), but it was a bad idea to mix something so surrealistic to suddenly be restricted by the realism of manga.
Spongebob looks like a kid in this when he's an adult. He works at the Krusty Krab. Patrick looks like a kid as well. Squid looks like a teenager from some random anime that no one has heard of. Patrick looks like a fat kid.
Wen I saw this I nearly peed maself. 3 letters...LOL!!!!!!!!!!!!!!!!!!! TIS SOOOOOOOOOOOOO FUNNY!!!!!!!! I is sooooooooooooooooo glad that Patrick be wearing a shirt. U Know wots weird? I HATE Spongebob Squarepants but I am favin this...CUZ ITS SOOOOOOO FREAKIN AWSOME!!!!!!!!!!!!!!! Sponge actually looks kinda cute (Squee cute certainly not luv cute) *favz over and over*
Quite good! Pat looks a little weird, but it's still good. Squid looks grumpy and generally PO'd, which is perfect. I LOVE how you did Spongebob! And the fact he's holding a spatula! Great job!
