Thanks Roger, I appreciate the feedback and criticism - I need as much as I can get as am still getting the hang of the gear I'm using (big step up from my old Canon S3IS)
The R-Rocks are a composite of 3 shot HDR which could explain the "weird" look, that could also explain the focus as they were hand held and/or depth of field not right as well.
All were taken with a Canon 20D + Sigma 10-20mm
KI sure is a fantastic place.
