Well I have seen some of your comics, and it looks like a lot is done in pencil. I used to do mine in pencil (no inking) and I opened the scan in Irfan View (a free image program, nice to use, I find Gimp too complicated
http://www.irfanview.com/ ) and I go Enchance Colors, and I select the GAMMA portion (which I think you can find on other programs too.) ... Its starts at 1.00 ... I used to turn mine down to .60 and .30 to darken the pencil to look more like ink. (Gamma does not effect absolute White (255 all colors) or Absolute Black (0 all colors))
Note: Gamma always starts at 1.00 for current image... .01 to .99 is darker and 1.01 to 6.99 is Lighter.
What I ultimately ended up doing was drawing everything with pencil like I used to do, and then Scan it and make the whole comic (minus the text and such, but I would add the frame lines (100% black)) then change the gamma to maximum dim. Print that out, then INK over the faded lines to a crisper (less scetchy) look, and then scan that page in, and put the finishing touches on.... (I use MS paint for forming and editing, and text).
currently I am trying out Trace paper and Ink over my pencil works. But if this helps you get some ideas, cool.
I don't mean to impede your style, I'm just saying this if you might find it useful.
So if that is something that will help you out with your backgrounds or something, if that is what you'd like to do anyway. You can test it out with using color pencil too, but I find that you don't want to move the Gamma too much, but you can also darken your color pencil as well. But can get a bit touchy depending on how you want the image to look. .. its just that pencil in an form or color does not seem to scan very well, especially for resizing to smaller images.
so just my ideas, But still, sometimes the pencil backgrounds kinda look cool behind the inked characters, as if out of focus... which may be what you are going for anyway :p
