If you are trying to go for a true planted tank, I would suggest taking the airstone out in attempt to keep as much CO2 as possible in the tank. If you have questions about CO2 and lighting, see the pinned topics in the planted section.
It looks great and will look even better when the plants fill out!
thers is acually nothing wrong with having it just that you plants would be alot better quality without it but as you only have a few it should be okay in my experience i ahve a tank used to ahve an airstone and a few plants all went well
tho i would recommend turning it off at night i have had alot of problems with a faulty 1 it kept backwards scyphoning the water out of my tankwhilst i was asleep now i disconect the air line and raise the whole thing up
The smaller plant is Lilaeopsis and demands high light and CO2 injection. You will also need to remove it from their pots and plant individually using tweezers.
The vallis and Hygrophila should do ok, they're much easier plants.
Consider adding more plants. A sparsely planted tank is a recipe for algae, especially with any direct sunlight.
As suggested you airstone will be stripping the water of any CO2, but it won't make much difference with your lighting (I assume you have one or two tubes).
Definitely avoid airstones though if you do inject CO2.
