Humm.. can concur..the first image I sold was full of noise, etc., and enlarged too much. I should have told the purchaser that a 15 inch width was too much. Anyway, no complaints from them.   I wanted to do better but that was a while ago with a now very outdated digital cam which was "state of the art" at the time!  Who really knows what folks want or appreciate? Being in a retail business not related to photography, I have learned in 30 years not to try too hard to predict the likes and dislikes of others.

Congats on the sale! Yeah!  and...sure, go for it in the classes.         Tom.
