Hi Kevin,
I like the composition, with the old and new side by side, but:
I'm struggling to find any important part of the shot that's in focus. I'd suggest using centre point focusing and choosing what you consider to be the most important part, so that's in focus.
At f4.5 you're going to get a shallow DOF. Abandon program mode, set the camera to Av, gain control of the aperture and use a tripod if necessary.
I'd be tempted to remove the dead twig in front of the larger mushroom, and possibly the bracken frond in front of the smaller one.
The red berries add little to the shot - the mushrooms are the stars, but since they're there it's OK..
The cap of the larger mushroom is completely blown, and the smaller one is almost so. If you shot in raw you could probably recover some detail.
Best wishes,
Stuart
