A shallow walk in the park!

I have been shooting a lot of landscapes lately f8/f11 stuff so this evening it was all about the shallow depth of field. Went for a walk in my local park, this is the result. Any suggestions, comments, critiques always welcome.

good job in switching it up.

i like the variety here as well. Dig the comp in shot one - the dramatic light in shot 2. For shot three I'd pump up the contrast and try some selective sharpening. I dig the comp and selective focus in shot 4 but wish the twig itself was a bit sharper. Hope that helps - marko
