Very nice final version here. I like how you cropped to bring us closer to your main subject. The original was good but bringing us closer to your main subject is a definate plus especially when you can see more details. In the close-up version we really get to see the details in the 'hairs' on the upper body of the bee and the eye (love that gleam that really comes out and is more noticable with the post-processing). I also love how the background colors have shifted to a more pastel hues - perfect complimentary backdrop for this bee for it invokes the idea of Spring with all the soft colors of that season in the mind of the viewer. Well done.
i agree, i think the orange compliments the green much better. the color change is verry smooth and i like the omission of the exrta branches. nice work.
