Suzi, This is how I would crop it. If you want a guide for cropping by thirds, just turn on grid and in preferences do 33% with a subdivision of one. This crop puts the bee on the intersection of lines in the upper left of image. I also added a vignette (under filter>correct lens distortion) to darken the edges and used the lasso to select,feather and copy the bee to a new layer where I put an omni spotlight on it and dialed back the layer opacity to make the bee stand out more.
