Need an advice

I started drawing about 40 days ago. I have some good pics but i still dont know what kind of pencil i should use :( give me some advices about starting and other useful and remarkable things about sketching. Thank u all at all!

Try it in the concept art forum, they know this better then people here.

I have already done it... but nobody answers ;/

Wait a couple of days, not hours, before you make another tread.

Hmmm, I'm no expert, but I draw the odd time. I prefer using charcoal pencils for sketching, gives it a nice look.
