Composition - First thing I noticed when I saw this picture was that the bug is a little bit small for this shot. I wanted to zoom in on him but obviously that is not possible. His placement is too far up in the frame. This photo I think is applicable to the rule of thirds, put him on the upper left side but more towards the center of the picture. The banana is also a little dark in color from what I can remember about bananas. I don't know if it'd been sitting out awhile or a color adjustment was made post shot. I like the fact that we can see some of the peel, but I think it might've been conducive to show some of the outside of the banana, to add a bit more color into the mix. Maybe some of the color problem could've been alleviated with a little more light.
Technical - Regarding the lighting, I don't like the shadow cast on the banana by the peel, but not sure if you could effectively remove it. Its pretty crisp and clear, no real problems there. A little more exposure probably sounds easier said than done, considering this insect is alive and probably has the attention span of my 6 year old. Not a badly taken photo.
Overall - I don't think these subjects have the potential to generate a lot of score. This image is lacking a little in visual appeal, excuse the pun. There isn't a lot of color and really nothing extraordinary happening. I think you did pretty well with this picture in terms of taking it, but there are some things that I would've changed had I taken the photo. But it's not my photo, so I'm just here to tell you what I think. Best of Luck in future challenges - Bob
Super lighting here, and I love the very close up viewpoint. The bug does not add all that much interest for some reason (at least to me). I like the banana itself because you've done such a great job with lighting and composition.
The color on this seems off. I am expecting to see a creamy yellowish color on the banana. Possibly a bit oversaturated and in need of a touch more light, larger aperture. May have brought more detail to the fly also?
My first thought was "Another banana shot", so feel it lacks a little in originality because so many other's entered banana shots as well. But you did get a double B for the challenge, so gonna award you extra points for that (and I do like your choice of background too)
