Some great shots for your 52 so far. I really like your tool of the trade image. Nice and sharp and works very well with the shallow DoF.
Ability is a cracking shot. Great colour and great use of DoF again.
I like both shots for depicting a book. Pity that the feet are cut off in the second one. Zen and the art of motorcycle maintenance is a book I have always wanted to read but never got around to it.
