for chibis it takes me about 30 minutes and for more detailed things it can take me from 30minutes to an hour

Oh man! I wish I could be that efficient O:

My full body marker traditional ones average 2 hours start to finish

Depends on the character, scenario, and commission for me!
Lineart itself, for me, takes 2-4 hours. The rest is a breeze. I'd say a two charactered fullpiece would take me roughly...15 hours? Something close to that!

oh phew glad I'm not the only one that's landing in the 10+ hour region!

A full day or so... just with any media...

It really depends on the characters drawn, the subject, poses, if theres a background... etc. But I average around 4 to 5 hours a piece.

For me it's was about an hour per character as long as I don't get caught up on one aspect of the drawing... But my art has been taking me longer now, I've noticed... It's kind of annoying as well when the pose you where trying to do, just doesn't work...

These take about 30 minutes per character for me - http://www.furaffinity.net/view/17979163/

A chibi with cleaner lineart and flats takes about an hour and a regular fullbody with clean lineart and flats can take me anywhere from an hour to three hours!
