I empathize here because I've shot in a similar fashion, trying to fit as much into a shot as possible. Sadly, it rarely works.
The highlights are blown out on the arm of closest chair and that whole side of it looks quite oof. Crop is very, very tight on all the chairs, lighting is flat, giving entire shot a washed-out look. Compostion is quite cluttered, with one chair piled atop another and that atop yet another chair. Background of fallen leaves just looks drab.
With such a selection of chairs you could have made the pinky Adirondack chair really pop, by putting it between the two metal patio chairs and shooting perhaps another foot or two to your right. This was an Advanced challenge, so you could have used a magnetic lasso (or similar tool depending on what pp program you have) and really blasted the colour on the Adirondack.
An aperture of 4.5 is quite shallow, even just a few stops down (say f.6 or f.8) could have made a world of difference. Going by the fast shutter I'd say you shot handheld.
FWIW: In a word: tripod. Even if you only use it for shots like this it's well worth it, because then you can close the ap wayyyyy down - try f.8 - and leave the shutter open for at least a second.
Hope this helps, and as I learned awhile ago: you have to take a good shot first, because all the pp in the world won't help a poor one.
