We're sharing a lot of the same plants there.
YOU asked so I'll tell ya what I'd do
Trim the Rotala to about 1-2" under the surface (and yea I know it will be back up next week)
Take all Crypto's and plant them all in 1 corner (spaced apart but closer together as a "group")
Then move the DW fwd left say into the left front corner and angled backwards a lil (diagonal)
Also what often helps the overall look of plants & fish is adding a background. Specially with the light sand, I'd suggest some dark blue or black. If you have a piece of construction paper around the house, hold it behind the tank, you'll see what I mean, makes the plants stand out more
