Telling true, this photo is one of the most wonderful macro shots I have ever seen here, on deviantart! It is so stunning for me, let me tell you why.
First of all, the composition of this photo is just amazing. I like when there is half of the photo blue, and on the other side the other colour contrasts well with the background. Also, the brown part of the branch makes this shot clear, so when I look at it, I immediately know what the main object is.
It is good that you focused only on the insect, leaving other details blurred, as well as other petals. And you caught the bee just in the middle of its job! When I look at this photo I become calm at once.
Let's face the truth: there are many such photos on deviantart, so this one is not so original, but still the composition of your artwork lets me think that this piece of art is unique somehow.
Well done!
