Excellent approach to bluring via manual focus, which is harder than it looks. It is easy to get an image that just looks badly focused. This one still has a well-defined subject, and the short shutter speed kept the person from looking mushy. Your choice of tone and brightness cap it off nicely. I think it should be framed and displayed prominently, maybe in a recreation center or school.
Ahhh. A summer day, the warm sun gracing everything with a glowing, golden color. My eye sees the abstraction of a tree branch until it slides downward and discovers children playing, laughing, jumping, and turning cartwheels.
This is really weird cause I kept thinking last night "what if I went out in the yard and did a cartwheel." WHEW, thanks. You did it for me. ;~D I like the high contrast and the almost toy-like shape the effect creates.
