Not sure what it's about really. Bit of time off and excited kids thinking some fat bearded geezer has just squeezed down a 400x400mm chimney to drop off a load of pre-wrapped prezzies. I think the lighting in your pic is great & soothing and elements of the composition are good but as a complete image it just seems a bit random. For me there is too much space on the 'cotton wool field' and the foreground cotton wool is distracting a little and there is no main focal point hence my initial comment.
