comradvolk: This is not great work, and his neck is not the size of an elephant's. Please post something useful next time, or we will make sure that you do not post at all. We promise.
CODEONE: You have a strong light source, which is a great start. However, you should think more about your colors, your character's facial anatomy, and the folds of the clothing. Right now the piece is looking jaggy, dull, and washed out. Don't be afraid to spend more than 10 or 20 minutes on your work! Especially when you are starting, even if you have a lot of traditional training, there can be a ton of trial and error and experimentation to get just hte right pixels in just the right places. If you don't put in the love you will not get the strong piece you want!
