do write abit more on why you've chose to post process the picture this way. there has also been an increase of titles with '' ??? 1st shot'' ''1st try'' etc. please avoid using titles like that as they don't mean anything to help in the critique.
I think he used zoom effect then unmasked the child.
This would've been more effective if the child was in some sort of movement (i.e running or walking towards you). The zoom would've emphasized the movement. But in this case, there is no movement hence, the addition of this effect is unnecessary IMHO.
Try shooting this at a lower angle (child's eye level or even lower) and try and experiment putting your subject right smack in the middle and moving your position a little more to your left. I know about the rule of thirds and all but there are exceptions to this rule.
Don't worry too much on your ISO setting. The noise isn't that obvious any way (Canon?).
Kids are quite fun to shoot. I guess that's every parents first subject when they buy their first cameras. That was one of the reasons i bought one. Keep it up!
