rainbow has a point.
Tall & more narrow would probably be better.
That and replacing or moving, or better situating (with mulch or something) whatever it is that's hunching over the lawn in the front of the beds.
Whatever those plants are look like they're higher maintenance or more protection than they've been getting.
From the way the colour is from one side to the other, plant to plant and from the angle of the sun in the pics... they look like some are either getting too much sun, or too little water for the amount of sun.
But rainbow's other point is important... what time of day were these pics taken and how much sun does each side get?
From the angle of the sun in the picture... it could be that it's just not going to work out to have the same plants mirrored on each side... because one side may get a lot more sun than the other side.
Being that the steps go right up the middle in the front, I could see the temptation to mirror plantings.
That's probably not real low maintenance though, when plants have different needs on either side.
You can still get a nice look even if you have different plants planted on either side... A good trick with that would be to use either one set of 2 of a plant that does well in both situations (probably rare), or some non-plant decorative item pair, where you put the same thing on either the outside corners, or somewhere at the same point on either side, to anchor the look for composition.
I've seen some of my neighbors do this... with like some kind of statuary that matches their porch/house. But then they have different bushes & plants on either side.
I've also seen some neighbors try to mirror their plantings, and the one side always looks shabby compared to the other with the exact same plants. :/
Sometimes you have to accept that plants have their needs and they're not going to just change to your needs.
I'm so glad I don't have any symmetrical structures or viewpoints like that in my yard! LOL
I have a hard enough time making things look neat in the front with my fast & loose gardening. ha ha ha
