Awesome! But i think I've seen this before?

Yeah indeed. Well done, but I've seen very similar things done by a company called "Drunken Munkey".

I swear, when I made this I never heard of "Drunken Munkey" until you mentioned it.
So i did a google search and came up with this http://www.cubico.com/estilo/estilo/drunken.gif it’s not too similar, they are both legos, and in some way involve marshal arts and the color yellow. Thats about it. If you think its too similar let me know.

Looks good, maybe make it a bit smaller though, have you tried a blue background it might bring out the yellow more

It's nice, but WAY too big.

I love lego men.

It also resembles a Brian Sumner Birdhouse pro deck: http://www.utilityboardsupply.com/product_information.asp?number=BHD060&back=yes&dept=1012&last=1009/?rc=bh

why does he have the small lego pants on?

HA!

haha legoman! change the colors to blue & red so it vibrates...nice

this has MALL written all over it.

sure, the design is allright. But please take away the background, you can´t really see whats the shirt or what isnt.
or, make the background a little more lighter?

hehe

Drunknmunky did make these kind of t-shirts but have scince stopped producing them, I gotta say, theres were much better too! http://www.comparestoreprices.co.uk/designer-t-shirts/drunknmunky-lego-man-tee.asp
