Are you in Florida? ( iguana ? Not in Brooklyn.)
First, beautiful work!!!
Second, my suggestion:
Those are very tall raised beds. How much rain do you get in your area? It depends on the percolation quality of the earth the raised beds are on. If the percolation is not much, the raised beds can become bathtubs and your plants can get root rot.
I would drill small weep holes in between the blocks on the bottom run of the blocks and put a bucket of gravel around the holes before you pile soil on top. You put small drain hole even for small flower puts to avoid root rot.
Lets see some green stuff in those beds. :-)
