Us poor new people do get overlooked in the 52, so here are my views:
Single: Great interpretation, as has been said the colour looks off, but other than that.
Shoot: Again, very apt. the left of the center leaf looks a tad bright, but the out of focus area is good, and the shallow DOF is very well used here i think.
Quad: I have no experience of shooting animals so i cant comment on how well you've managed it, but #4 is great, #1 is the best of the moving, its a shame the ball block out the dog in #3.
Produce: certainly fits the theme, good contrast with the red/green, almost christmasy.
Candid: Well poor Ollie has a cracking expression there, and makes a great candid shot!
Chemistry: I had to read the write up to understand the connection, i think this isnt your strongest shot in the 52
Play: number 3 is very representative of the theme, and th best of the bunch!
