To what extent would you like me to re-crop it or re-size it? Just want to make sure I'm on format for what you're requesting.

It's entirely up to you. Here are some things to consider:

1) - Most people cannot see your full-size images. All that they can see is the image above the comments and the thumbnail shot that they clicked on to get here.
2) - Cropping always reduces the file size. So, a very large sized hi-res image can be cropped to reduce the final upload amount, for websites like this.
3) - Cut away as much of the background as possible. The background is completely useless and it only detracts from your image of the moth. It makes your moth look smaller.
4) - Square crops are the best shape, but they don't have to be perfect squares.
5) - You can click on the images tab and see (right away) how your image compares to the others, by looking at the thumbnail shots.
6) - You can edit and replace your images anytime. You don't need to repost and you don't need to add images.

Please let me know if you need any more help.

That clarified things a bit. I reduced it to square size and cropped out more of the background. Hope that's better.

Also thanks for the ID!
