Nice closeup of the center of a tulip... I have given up on trying to photograph reds like this with my 707. Maybe the 717 does a better job of this :)
Your composition here seems to be fine... I prefer the off center perspective you chose and the square framing works well with that choice.
Unfortunately, I don't have a lot to offer you on this photo as far as critique is concerned. This particulary type of shot is a favorite of many and you have executed it as well as any.
Great intense colours. The composition of this is almost exactly the same as another photo I've voted on, but this is far more dramatic and interesting. Nice work.
The composition and lighting are great! Super choice for the challenge! Your framing and angle of the center flower is breathetaking. A solid 9 from me!!! Great job!
Great macro. These are hard to do for so many reasons (which is why I don't do them). But you've done an excellent job with this. Excellent detail and exposure.
