You don't suck. You're just new and made some novice mistakes.
You focused your attention on effects, and neglected your focal.
I suggest only doing this with landscape, smudge, or abstract pieces
If you are new with Ps you're doing ok, just observe tutorials and pick up anything you can.
for beginner, i'd rate it 9/10
Conitnue like this and u will become an great artist.
