Not being a jerkass or nuttin,
but why do you think its poor?
first of all, the size, it's a little out of normal sig size.
And you say it is a sig, but it looks more like a banner.
About the work itself, I like the sepia colors but they don't match mario.
Mario is a fun happy character, and sepia makes it sad...
the M on the cap is totally fucked up, and red??!! So all mario's cap is red but only the M has it's real color?! If you were thinking on going Shindler's list on this, you kind of drift away from that.
The brush work seems great but the sepia once again ruins the great brushing work by hidding it.
