Nice paint job, but the pint trees look like they were designed for a much smaller scale. (Unless he is a giant wood elf.) Generally speaking 3' and 4' pint trees don't always look as "full" as their older 20' cousins.
(6.5) Something is bothering me about those trees... they are too regularly conical to be seedlings. So they look out of scale :( Otherwise, not bad though your highlights could be smoother.
