How balanced does this setup look for a beginner?

Hey everyone,
I’m just getting into LRF (Light Rock Fishing) and recently picked up this beginner setup (listed below). I mostly plan to fish from rocky shores and small harbors in the Aegean region.

How balanced does this setup look for a beginner?

I’d love feedback on:
1. Is the Ryuji Voltage 0–5 g rod paired well with the Ryuji Ajix 500 reel and 0.04 mm braid?
2. Should I go for a thinner or thicker fluorocarbon leader (currently using 0.18 mm Daiwa Prorex FC)?
3. Are my jighead and lure weights okay for Aji, small seabreams, and gobies around rocks?
4. Any suggestion for soft baits or metals that work better in Mediterranean/Aegean waters?
5. Would you change anything before I actually hit the water?

Any advice or tuning tips would be appreciated!
