I met mark and got his comics Cobalt 60 The black and white, you guys have a similar style that I love ! And in color, don't even get me started, you guys are crazy with colors ! Keep it up man, you bet ima get some of your comics !
you can also do it in color when the image mode is set to CMYK (so you have the original print style halftones), and then just set it back to RGB when putting it on the web. looks then like this ralphniese.deviantart.com/art/… (here's just an old scanned paper laid over the picture)
