Nice Tim - the quality of your lens really shows here.  The "up the tree" shot is well-done.

Am going to send you my Autumn 2009 shots soon - could not believe how beautiful the Cherry Trees are in Antumn - when I was there, NO ONE TO BE FOUND!  Amazing, then a gal ran by in a brilliant purple top, and I caught her exactly where I wanted her, away from me so as not to make her the focus but the contrast of her purple top with everything else around me.  Give me a yell when you get them.
