This is a decent shot - the time of day (lighting) makes it a bit challenging as some of the whites are a little overexposed. Where did you set the focus/metering? The white on the front of the canoe would have been a good steady spot to get the metering correct and with enough DOF would not have impacted the focus for the rest of the people, etc...
What got lost in the crop? If you cropped water from the lower section that's probably best - could have left a bit more trees in if they were there.
Anyhow...good job overall. Keep smiling and having fun!

For what it's worth, I'm pretty sure that's a fiberglass canow, based on the look of the gunwales, with a faux-wood paint job. Nice shot though; they're having fun.
