Nice colours that work well together, good choice of set-up, maybe wipe the finger print off the end of the knife but thats the only thing I can think of to improve.
Great perspective and DOF. Can see a fingerprint on the blade even. The two things that brought this photo down some in my opinion is that the yellow may be over saturated a bit, and it makes the top side overbearing. And the shadow is a bit distracting for some reason. The way it shows real well on the bottom of the banana is geat and the little bit that shows another section a bit higher, but the way it is cast on the mat distracts me for some reason. Wish I could figure out why
If I see another banana photo I'm going to scream :) There - I feel better now.
Apart from being (another) banana, it's a great shot !!
Bonus points on the other banana shots for the Blue background and the Blade :)
Hope there are no forensics people here cause they'll probably try and lift those prints right off that knife. Great detail, nice use of shallow DOF, and colours that grab you. 7
