Black And White Photography Portraits

for my photography class, I have taken two self-portraits?

I know http://i433.photobucket.com/albums/qq55/HaleyD9/IMG00079-20091024-1151.jpg http://i433.photobucket.com/albums/qq55/HaleyD9/6.jpg the latter is different, but I wanted both to show two things I agree they are a little blurry, but I can not take them again before having to submit
Self portraits are difficult simply due to how does an autofocus camera, since even in the timer mode it tries to focus before the timer starts. Have someone stand in for you while you press the button works very well for a self-portrait. Or to stay there, you press the auto focus, then take your auto focus camera so that when you take a picture of you, it is pre-targeted. I two of your ideas. Your first image is more exposed to my taste, however, that my photography instructor always said, if that's what you wanted to do so it seems. I like the emotion in the second image.
