This is what I do at work (comic strips!)

This is not newspaper friendly.

It seems somewhat disaffected, mostly because I don't sense a lot of cohesion between each strip. Three samples isn't a ton to go on, granted. How much do you know about your characters? What is the purpose of their existence? Basically, what's it all about?

Visually, I like the basic body designs. The skinny leg thing works. Stronger differentiations between heads will be necessary though. I gather these are rough sketches, so I'll just hope any final versions will have cleaner lines, standardized fonts and better page structure. I think you may need to experiment with stronger visual contrasts in the designs and line thicknesses. It really makes certain characters and settings pop. If it's meant to be a webcomic, you're not confined to the dimensional limits of a newspaper page, so there's no reason not to add more visuals when able. It needn't be excessive but they do add a lot and describe settings in a way that allows you to conserve word space for edgier humor.

Show me more and I'll see what can be done with it. You may wanna seek out Dubble and ask his opinion too.

Jam it back in, in the dark.

Just for kicks, I decided to draw your character myself. I tried to remain as true to your style as I could but little bits of mine show through. My tablet's not connected so I just did it with whatever pen was lying around. Here's what I wound up with:

Not too bad for about five minutes.

There's nowhere I can't reach.
