Old old internet comic (as much as 'net comics can be old), basically helped found 'sprite' comics on the internet - web comics using video game sprites instead of drawings. The most famous is probably
www.nuklearpower.com , aka 8-bit Theater.
The comic has spawned a large community of spinoff comics, and a wide variety of 'custom sprite' artists. If you're looking for more spriting help, you -could- try asking around over there.
