leah clearwater..... again

well here's one more drawing of leah clearwater, hope you like it.

my scaner makes the dwaing look lighter, so I tried to make it look darker with a little edition and now it looks better than the original...

I made it with pencils .. hb 4b 6b , for being honest I'm a little bored of using this material, and as I know nothing about artistic techniques , I would appreciate if you suggest anything..., maybe other pencils, types of charcoal... I don't know, whatever you think will be well received.

thanks !!
