This is a beautiful photo, with great comp. and great colors. But the boy is nearly invisible. And I'm not talking about the ghost effect. He is just too far away and his color is not contrasting enough.
Otherwise: :thumbup::thumbup:
You had a good idea and the pic of the scenery is good but I think the person is a bit far away not really in perspective with the whole scene. Good idea! I bet your brother liked it.
