Just started, seeking for critics and advice.

Hello all,
Just few monthes ago I watched some of Mark's videos and asked myself "Why not to try? I always wanted to draw."
So in December 2013 i tried to draw at least something, here is the result:
First attempt

Then I made myself just sit and draw for few days, that what i came to:
My first hand

And I wanted to try draw some anime things:
First Chibi
Horo
Slavegirl
Girl on the roof
Girl on the roof 2
Masami Iwasawa and roof girl
Magus
Some other works not related to Anime
PTRD
My first EYE
TIE fighter
TAU Fire Warrior
Greek helmet
Deamon wing
Dragon

That are my works (not all of them) for 3 months from the first day i picked up a pencil.
Please comment them, I welcom any critics for any pictire coz in that way ill see what im doing wrong. Any advice will be helpfull as well.

And thank you Mark! Your videos really insipre me and my dream will come true when my skill level will be not far from yours (bad there is no a lot time for drawing coz of job )
English is not my native language, sorry for mistakes.

Regards,
Shuul
