That's a nice pic
All of the characters are easily recognisable... only thing which I'm not so keen on is the colour of Sal's shirt - the green is way
too bright. Also it would be useful if you rotated the picture and just provided a link to it so you don't have to tilt your head to read the quotes.
Incase you didn't know, there's a pretty large fan art section here
on The DOD
which contains a lot already. You may want to submit yours there too...?
