I see some Hydrotriche mades its way into your layout (far right side) . You have many difficult plants growing quite well. Quite an achievement for a first effort. Now develop a mid-ground on the right side, and watch how much bigger the tank will look.
Personally I thought the colour scheme looked fantastic prior to the addition of the "grass", the fish and plants were offset gorgeously with each other and the white sand substrate... The pinkish and blues worked well
Now, it also looked great when it first started and had a lot of greenery around the back, gorgeous.
It still looks good now, I think it's just missing the 'woah' factor it had before... it could just be it's a different type of woah.
