Hello, people from conceptart.org

I am new here. My name is Peter, I am 18 years old boy from Slovakia. I know this place nearly half year, and today I decided to join.

Last year I found digital painting on internet and I started to be interested in it. I bought tablet and started trying, but it's useless without knowing basics. I started with 61 poses from posemaniacs, 60 second each. I found it difficult, so I have to practice it more. Then I did some studies from Bammes. I wanted to scan it, but it didn't look very good, I rather took some photos. The last thing is my study from life, some glass cup.

I'll be thankful for every critique and advice.
I hope I will be able to update every week. I hope I did the attachment stuff right, and thanks in advance.
