I like it! I think its very artistic, you did a good job with background, middleground, and foreground. I think keeping the blue lake in the corner nice and touched-up will be some work but if you're up to the challenge then go for it! I can picture you picking each brown piece of gravel that gets in there out with tongs or whatnot, and that must be tedious!
But anyway the tank looks great!
The bubble wands are not necessary but look good, that also gives the tank some personality as well. They might pull the C02 out that you would otherwise want for the plants.

Bravo, thanks for sharing the pic!
