Not a bad looking tank Ernest. It is hard to see in the photo what is happening in the back left corner. I get the feeling the photo does not do it justice.
The foreground and center mound looks nice, the two work well together. The glosso has a strange line near the front glass that is distracting and I don't know where it comes from. Knowing glosso though, I am sure it will grow out in about 3 days
I like what is happening in the center with the Pogostemon stellata and the stand of Rotala indica to its right. The R indica (or is that didiplis?) on the left either needs to go or fill in more. I find the limnophila to distracting in its present location, Possible it would look best moved to the back left corner, allow the H. micranthemoides to grow in some more and trim it so it tapers back from very low in the front to about 1/3 the height of the tank, where it meets the limnophila. Or, for the left side, try keeping the H micranthemoides low as a mid ground plant would work nice with a slightly taller stand of D diandra behind that and then the Limnophila in the back corner
Try to propagate your C balansae more so you have a little bigger stand right behind the thicker wood branch. What is the low rosette plant in the center of the tank? The leaves are a little wide for this layout, IMO but would look ok if pushed back a little farther so they are less prominent. Also, you should add 1-2 more these plants at the base of the mound just to the right of the ones already there. Adding 3 of these plants, or a denser stand of hairgrass right where the back glass meets the right side of your mound should add nice transition to the open are from the mound without making it look to filled in. Right now you have great depth due to the openness of the right corner and I would not add any plants other than what I already mentioned. If you do add something, I would recommend you use a very shallow stand of grassy plants like Vals, C. retrospiralis or Cypress. I would not add anything with leaves wider than 1/2" but personally I would not add anything. I might consider replacing the rosette plants you have with Bylxa japonica, which will stay a good height and have fuller but more delicate appearance.
Very nice tank. Keep up the good work and please continue to update this post with photos
