Normally I don't save high res images, but the composition and character used in this are awesome. However, when the resolution on your image is so high you can see every little squiggle and mistake in the inking of lines. That too big.
Someone ran some of that half tone interpolation bullshit on this. Drop it down by 75% (I don't want to get a ruler to count how big the pixels really are) and save it with less compression.
