I would change that background color to suit the colours of the furry dudes. Also borders with rounded edges and a 3px shadow around those bottom boxes, center justify the text.
When I go to phone resolution the video and the above opening paragraph is sitting on top of the background images.
I would suggest going with a 2 column layout and using % instead of direct pixel amounts where possible.
