Definitely getting a Sylvester Stallone vibe from this piece.

Rambo?                

thanks you to much, i fix it, sorry but when i see picture more times, i cant see details...

I think too it looks like Sylvester Stallone. ( maybe(? ).
nice color using.

There's one near-black pixel, 2nd row from top ;)

Nice, but far too much dithering. At least the central face areas should retain maximum clarity.

Hi, im sorry i just use colors from instruction. 8 as is on palette. Can you tell me what i miss? After i have no problem to fix it.

Thanks

one color too many for the challenge. could you please fix it?

That looks like Sylvester Stalone.

Great idea
