well done
I'd play a bit with making the stone look more haphazard, try tilting so they're not all level but have been there for years, also consider breaking into smaller bits - easier to attach mosses (you can vary the moss types for color & texture) & you can shift them about later to slightly alter the look or path direction ...
Yes "mini" is better for the Path
I like a mixed "meadow" look so you might interplant
E parvula
E "mini"
then
Then try some others such as
M crenata (I'm really liking this one at the moment)
M 'Monte Carlo'
Gratiola viscidula - which is very interesting leaf shape once it gets going, it's really quite slow so far in my tank
(I'm just looking at Tropica website (as that's what available to me))
I had great luck getting some 1-2-Grow plants going, not "Dry Start" but just planted into Tropica substrate, then partly filled tank to maybe 10cm water column, no water changes or livestock ... plants filled in fantastic & no "melt" after I finished filling tank, adding filter & heater & shrimp etc
None of this was planned of course, just got busy after the initial planting & it was 3-4 weeks before I got back to the tank
