How does this sound for a beginner setup?

Hello!

I am starting a 20 long as my first planted tank and wanted to get some opinions on plant choice and general setup. I am going for a DSM/Emersed start to try and get the plants growing before eventually introducing my axolotl and feeder guppies as livestock. I plan to use excel once flooded.

Once everything gets here I will have:

20 L tank

10W LED floodlight

15 lbs black sand

Bonsai and ghostwood branches

Osmocote Plus root tabs

DHG

Cardamine lyrata

Rotala indicia

Alternanthera reineckii roseafolia

Bacopa caroliana

I'd love to hear a more experienced opinion on hardware as well as plant choice, or thoughts in general!

Thanks
