Mastering concept art - orkish chest sketching

Hi, guys!

My creative challenge goes on and on, and by the way I already told to my teacher that I will take the second course, so I have to tune on for two more months of instant hard work and drawing. And then three months more. And more. And such till I'll finish all the classes available:) 

At the moment I already feel more or less confident in what I'm doing. In the beginning it was really hard, but now I feel more ad more confident. c

Today I want to show some sketches I made for the concept art task. I'm sure you remember my ork girl who was warning spammers in the bottom of each post. So, I decided to create a chest that belongs to her.

So how creepy the first three are? But I really like the sixth one and probably I will work on on it's base.

These sketches took me about 4 hours in total, plus an hour for these three:

Actually I needed to make 27 concepts, but had not enough time.

Next week I will show how the chosen chest evolved to a more detailed and well-drawn object:)

Love, Inber

P.S. Nearly forgot! Now you can find me on Weku, nickname is the same as here:)
