Hi Max
you have posted some very nice photos here....well done.
My comments for each are:
#1
I really like the
graphical illustration look about this shot. My only critisism is that the shadow seems to play with your eyes and takes some attention away from the petals of the flower. Perhaps the shadow could be faded/muted so it doesn't stand out as much, but is still evident to portray the 3D look ?!?

A beautiful, crisp photo which stands out well from the nicely OOF background. Great use of DOF in this one. The darker background areas really help to lift the brighter petals towards the viewer. Again, my critisism is the blown highlights at the ends of the petals. More definition by exposing them for less time, I feel, would make this image even stronger.

This is a really nice photo and I like the exposure on this one, though the DOF could have been a touch shallower, to blur the background (just my preference). The flower in the top left is partially cut out of the frame. This image would have looked stronger if the entire frame was moved to the left to include the whole "top left" flower, and remove some of the space from the right side of the orange flower....IMO.

The OOF flowers in the centre of this image detract from this too much, for my liking. It also looks too busy. The Lorikeet seems to get lost in all the fine detail of the multitude of smaller flowers. Perhaps a crop around the Lorikeet, leaving some of the flowers to border the image may work well here (although I guess it depends on what YOU are trying to achieve with this photo). The bird could be the secondary point of interest in this image (the flowers being the main point of interest), in which case, my suggestion would lose it's merit.
Please read this as constructive critisism
