I love your scape! The rocks are perfect. I've been told to get that perfect-looking planted scape with nothing but beautiful tops of the plants, to pull up the whole stem, cut it off where you want it, and only replant the tops. Once I got as many as I wanted, I started doing this, and it does look better to have nothing but tops instead of stems and forks.
When I can no more stir my soul to move, and life is but the ashes of a fire
When I can but remember that my heart once used to live and love, long and aspire
Oh, be thou then the first, the one thou art, be thou the calling, before all answering love
And in me wake hope, fear, boundless desire.
