Looking for critiques. Amateur photographer. Thank you

Kia ora,

Unfortunately, it won't pass Adobe quality criteria. There are two many issues:

• focus - not sharp as it could be
• artifacts - compression artifacts
• white balance - it's too magenta
• exposure - you need to make the photo lighter. It's because you used a telephoto lens, and in addition to that, you have got vignetting - light fall off from the lens. Lighter in the centre, but darker around the edges
• noise - you have a high ISO - 12800
• you're missing contrast as well. No whites or blacks

This is a 100% crop:

Again the result of using a telephoto lens. You have to balance out the exposure in post.

By the way, did you use digital zoom at all?
