Hmmmmmmm I dunno really xD I've heard some people point out that they like the photoshop brush I use for sketching and inking, which is just a hard round brush that I fiddled with a little bit to add some slight variation/texture. Mostly because I don't like the perfectly hard edge of the regular hard round brush and wanted a look closer to traditional inks with my digital line work.
It's kinda hard to see at the scale most of my comic characters are at, but you can kinda see the effect on the panel outlines which I stroke with the same brush:

Other than that... maybe just a slightly higher than average amount of backgrounds? I don't think it's that uncommon for action/adventure comics, but for example in the pair of 20-ish panel each episodes that i'm working on right now, I think only like 5/40ish panels don't have bgs drawn in. So yey, backgrounds lol
