Powerful image. 1/125 with a 600 Hand Held! You must go to the gym often! I hope the gator didn't know you couldn't back up any more. I like the image, but would consider adding canvas on the left.
Not much gym time... but some. I also beat the crap out of a 100 pound heavy bag every now and then but that's more for stress relief than strength training (but it does help). Using the 600 hand held is a good workout... no doubt about that. I took some shots of the same gator today (it's got some damage on it's back from another gator). I used a 70-200 but you know how it goes... they never seem to strike the same pose so I didn't get anything that I really liked. At least I don't think that I did...
Very nice in your face image. I'd crop off the right, since that part adds nothing to the compo and is behind the subject. Moving the camera to the left would have been a good move.
