Nah I reckon leave it alone, it in the overall scheme it's still a good tank. Photos always look a bit flatter than real life.
To create more depth for a front-on shot there would need to be more of an illusion of scale, so there'd have to be more smaller plants at the front and all the tall crypts moved back but with all your ferts n stuff there isn't much that will stay small. You could perhaps move the hydrocotyle and the other long leafed plant in the middle to the back but it's really just splitting hairs in my opinion.
In short, you like planted tanks and that's what you've got.
In double short maybe you could take the photo from a lower angle or from a corner so it's on a bit of diagonal and then we can see more of the depth that way instead. Might work, might not.
