First off, a big thanks to everyone who replied - I really appreciate you taking the time to give me your feedback and thoughts. It's surprising how much feedback from other artists helps to avoid that "Flailing in the dark" feeling. Now, let me see if I can answer all the various comments...
I prefer the second look much better. It's not as flat/bland! :)
A lot of people have echoed this sentiment. I'm torn because on the one hand I'd like to jazz up the art further, and show more of what I'm capable of doing, but at the same time, more detail adds working time and I have a hard enough time keeping the strip on track as it is.
I would judge this one on efficiency, does it take longer to do one verses the other? If so, go with the quicker option.
The first method is quicker, though it does require a lot more precision. Shading is nice because you can just dive in and swish stuff around. Flat tone shadows require taking the time to get it *right*. But still, the flat tone look is probably twice as fast as the shaded version.
The second is slightly more realistic and edgy. Which one fits your comic better?
My comic is as far away from edgy as it is possible to get ;) No, really, it's a bouncy, silly, feel-good strip that plays with horror and sci fi tropes. I'm frustrated because I like the second look because it reminds me of the great B&W horror & fantasy mags I grew up with (Eerie, Epic Illustrated, etc) but I'm not sure it suits the strip. More on that below...
the only real difference I see in how visible the black lines are in the second is in the hair and the shirt where the shades are way more visible than the black...though I don't think that is a bad thing.
That's a two-pronged effect. The shading draws the eye more, but I'd also switched from a .1 pen to a .005 pen for the basic lines on the second one.
Now, having read your comments and pondered, I went ahead and started doing more of the strip that way and almost immediately didn't like it. To wit:
I did the above, sat back and looked at it, and hated the shading. I have always preferred my unshaded inks to almost every type of shading I've tried, but this is a particularly strong example. But I'm not sure if others will feel the same, or if the "enhancement" of the shaded forms will be better eye candy for the viewer. To me, I think it crashes - I think the basic characters are too cartooney (intentionally) to look good with realistic shading. But I'm curious to hear other opinions.
If I had a goal, I think it would be something on the order of a Looney Toons look with a *little* bit more complexity.
