Initial impression: Very cute, almost expect to see a Jimmy Carter ref in there too :-0
Technical: Slightly busy in terms of composition; find it hard to locate the focal point, eye roves around too much. Ambient lighting fine, a little drab perhaps. Would look to see this closed down an f-stop or two, maybe slow the shutter to 1/80. On a personal level I think you relied a little too much on post-processing; on this site, you must still have a good, clean shot to work with. All the pp in the world will not help a poor shot.
Artistic: As already noted, the gravel in the upper left area distracts the eye from the scene in the foreground.
Overall: A good try, reminds me of my early days here - feel free to look at my first few dozen entries or so, they'll make you feel better. :-) Keep shooting, that's the only way to go.
Voters here at DPC will ding you, I fear, for the gravel (?) in upper left. Perhaps a different background altogether would give you a higher score for this. It, especially with the grass, seems a bit busy and competes with the subjects. Not voting.
