+1 and a nice tank.
The circulation can be tricky with Rotala planted so densely. Rotala is also super good at growing a ton of roots from the leaf nodes, making that stand of plants even more dense. The light penetration is also a challenge - I would guess that all the plants in the middle have very few, if any leaves ~2" from the top. This is where the stem spacing and trimming can make or break that layout.
Go for it!
