Welcome to the forum! Very good picture for your debut. I like it a lot. It's a very sharp image and composed really well. As for the *istD, there are a few users around these parts that have that camera. From what I've read and the looks of this picture, it's a good choice. It'll be good to see what else you've got to share.
Welcome and nice pic. Beware, this place is adictive The first time I clicked on Photoforum I lost my life and my nights are wasted here. My wife is not impressed
Sorry I missed this earlier John, super pic composition. You might try spot metering on the bright spot the next time you shoot these. It might work better for the highlights.
Welcome to the (very small) legion of Pentax shooters here.
