Fantastic! The young boy's skin and hair just glows with health.
As for the 'critique', What we see here is probably not exactly what we would see in 'real life' but on first glance, the white on the ear really does draw the eye, also I found the back of the neck too bright too, making it look like he's got a really skinny neck. As I said, it may be due to the problem of photographing and uploading, if not, I would put just a little colour there to solidify the balance of the neck versus the size of the head.
