The sketch book is too small so there is no room to rest my hand. It's a good size to put in a purse or pocket, but not really ideal for comfortable drawing.
The proportions got away from me because I didn't use any construction lines. I got caught up in the details too soon which I knew not to do, but I did it anyway. Bad habits are hard to break.
I am going to try to draw more guys because I hardly ever draw them and I need to get better at it. I tend to make them look feminine and I need to learn to emasculate them. Practice, practice, practice!
