Hoirzon line is too low.

kinda, I'd say a little more foreground below the figures is needed, whihc you could argue is the same thing.

this is a great homage to both sources. I love N.C Wyeth and think you did a great job emulating that painting and his style. Oh and your horizon line is fine, mainly because its in the same place as  in the Wyeth painting. This is true of all the major elements of this image. Again great stuff very creative

This pic is amazing.  I love how it looks like they are standing on a cliff, and it makes the gaint look HUGE!!!
