You guys take all the fun out of this D=. I was waiting for everyone to say "lol ur awesome" so I could look superior to them for giving actual criticism. Or for Faw to try to help you, so I could talk about how he was wrong.

Well, Mr. Spectro, first I'd like to say you are very talented and on a great start. You have no problem with drawing things from obscure angles and you seem to know anatomy well enough that you can make drawings that don't look "wrong".

The only real thing that could be improved much is how you stick to straight lines. In an organic drawing, having too many things that are vertical or horizontal looks unnatural. For example, the way both of Jazz's forearms go straight up/down, or Lori's whole arm and gun is a perfect horizontal line. Try to tilt stuff a bit more, to make it seem more real or 3D.

There's one big problem you are having, however. Let me give an artistic suggestion: don't use Paint. If you want to draw things directly into your computer, use Illustrator. People only use Paint when they want to show off how good they can draw with bad software. Paint makes jagged, blocky lines and has no layers and stuff. I pasted Lori into Illustrator and pressed "Live Trace":

The line quality is a lot better when converted to vectors. The lines are smoother and looks like you drew them with an actual pen, with ink. It'll also let you make little adjustments very quickly, probably cutting that 3 hours down into 30 minutes.

Or, if you don't have Illustrator, use Photoshop. It's good too, but best used for shading/touchups after you make an inked drawing in Illustrator or on paper.
