Hello,

To be honest, it looks like a snapshot of your cat! Focus, composition, and exposure.

Read these guides to get you started:

In addition to the great advice @Jill_C has already given you, there is some exposure adjustment needed, particularly with the white point.

From a composition point of view, there is a lot of empty space on both sides of the cat.  It might be worth trying a longer focal length that compresses the field of view more to eliminate some of that space.

Cheers!
