With both of the images above I have added Colour Dodge and Burn in Photoshop to enhance the depth of field. I removed the brown flower on the top left which was causing a distraction and drawing your eye away from the subject matter being the bee. The saturation has been increased to give the photograph more depth (I take photographs in RAW, which are flat images). With the crop I have taken out the fence line and ensured the whole flower bud is in the frame. I have also left space behind the bee leaving room for you to visualize the bee flying back before going to another flower. By doing the above, I feel that the tension within the image keeps your focus within the frame exploring the bee and flower buds.
With the above images I stood back a little further knowing that the images would need to be cropped. I wanted to capture the bee walking over the Allium drinking the nectar so I needed a slightly deeper focal plane. I cropped the images so that the Allium took up the whole width/height of the frame to highlight the size of the bee in proportion to the large bulbous head of the Allium, creating a bit more drama as if the bee was climbing a mountain of flowers. I positioned the plant in front of a tree, so that the background would be all one colour with different hues so that it did not distract from the subject of the image, but rather compliment it by keeping the background simple.
I increased the exposure on the bees to separate the bee in flight from the flower and background. I positioned myself looking slightly down onto the flower, so that the grass became the backdrop avoiding a fence line and a diagonal change in colour drawing your eye over and out if the frame. Without this line the image retains a tension keeping your eye on the subject mater of the image.
