The lighting in this is somewhat spooky, contrasted with a subject that is almost freakishly happy, and I feel like he's going to turn on us at any moment. Great colors, eerie but maybe that's just me ;)
I love Thomas. I first saw this show when I was stationed in the UK in the 80's. It always irritated me that they felt the need to be politically correct when they brought this show to the US, and they renamed "The Fat Controller" to "Mr. Topham Hat"
Works for me - properly framed, good DOF control and the immediate impression is whimsical without being over bearing. Nothing jumps immediately to the eye as out of place and the colors compliment the foreground and background. Well done and a solid entry into the challenge because of it's technical and artistsic success.
