Steph i love that Rockwell piece, it's great to see your take on it.
Not that it hasn't been mentioned before but all your colors seem to be in the same value even though people are on different plane in the picture (i.e. gorilla and kids foreground, dad and car mid ground, and mom background) you should try to play with the value of these colors and maybe even change the colors in some places Value effects depth more then color...infact value truly expresses depth color just gives it a punch and can affect the composition. Can't wait to see it textured, maybe it will bring out the depth in the picture more and help with the values cant wait to see something truly amazing, like we know to expect .
