thanks everyone for your comments which i really appreciate. I'm a beginner and noticed the spots. i thought they were because of lens fungus or something, but could not touch up the image due to challenge rules. i'll get the sensor cleaned.
ive experimented now with the image based on comments, like cropping, adjusting contrast, highlights and shadows.
my wife had been nagging me for under using the expensive camera, and i'm glad that i posted the image. her nagging paid off and i have leanrt more than a thing :-)
Oh man, I saw this one and thought 'wow...that looks cool! I'm sure I won't be the only to say...this would have place really high except for the spots. The sky is a tad grainy...maybe lower ISO would have cleared that up? Anyway, I still like your photo. I'll give it a 7+ despite the flaws. Good luck to you!
