I struggled to see the safety aspect of this at first... then I realised that it was the oven mit... I must be tired. So... extra points for originality. The shallow DOF works for this image, though, I think the colour of the glove doesn't contrast enough with the tray.
Yeah, nice. I like the shallow DOF in this shot. It looks like some natural light coming in from the right.. It might have looked a bit better if it was coming from the left, so it lit the inside of the mitt and the front cookie instead. Still good though.
