They look wicked tammy
Just one thing though, IMO, the white gravel washes the colours out.(says he with white gravel in one of his tanks ) Dark/Black gravel shows the colours up much better.
Just something to think about, not saying yours looks dumb or anything, keep up the good effort.
A few more plants would look wicked aswell
