I have had several pictures rejected.

I am fairly new to this and I've had several pictures rejected due to technical issues. Can you please give me some advice as to what I've done wrong with them so I can correct it? Thank you I've put some examples below.

Hello @default46obsig44ms8 , your photos are not properly focused. The subject needs to be really sharp. The last photo is also underexposed and poorly cropped.

Thank you for your feedback. That will really help me.

If you check your pictures at 100% and 200%, you will detect artefacts that you do not see at screen size. In the case of the dragonfly picture, you see chromatic aberration.
