snow in texas? Snowy Day in Black and White

These are some of the first images I've captured with my new Canon EOS

300D and I'm still trying to figure out what settings are right to use

at what times. I'd appreciate some guidance from those of you who

know what you're doing. I don't post-process a whole lot (see photo

details) mostly because I'm still learning my way around Photoshop.

Anyway, help with DOF, shutter speed, and post-processing suggestions

are welcome. Thanks for your time! :o)

Sorry, but its to dirty. It deserves a better retouch job.

You say it's dirty and needs a better retouch job. Please tell me what you mean by dirty and how specifically I can or should retouch it. Like I said, I'm new to this and don't know much so I need a little more direction. Thanks!
