Try getting near the ground with your camera for a different perspective. Pictures of the tops of mushrooms are fine for documentary purposes, but make for a boring photo IMO.

Something like this is more interesting and shows more of the mushroom. The underside is the best part of a shroom IMO.

You generally cannot control the placement of objects in nature photography. But you can control the placement of your camera, and you should put it in the most interesting places. Also, these aren’t paintings and they’re near instantaneous to make, and near-zero effort when compared with a painting, so make tons and tons of them: all the angles, all the lighting, color, black and white, high grain and no grain, snap-snap-snap-snap-snap, and then pore over all six hundred of them in Darktable when you get home, and pick the best one or two.

Get closer so that your subject occupies more of the frame. Use a wider aperture to get narrower depth of field so that your subject pops more relative to the fore and background. When possible and reasonable, control the light with... lights. Control in this context can be reflectors, strobes, snoots, gobos, flashlight, cardboard (blocking light from portions of your scene), whatever works. Try both natural and unusual lighting angles to get desired details to pop. Just be sure pay attention to color temperature of any lights you use.

If you're new to color correction and white balance, get yourself a calibration card. It can totally be a cheapie to start out. Hell, I still use cheapies. Protect it from UV light when not in use. Set the card in your scene at the beginning and end of your shoot. Those pics will make it easier to define baseline color corrections for your session.

Those aren't photos they're mushrooms.

If they're the psychedelic kind and you took too many, I can understand your confusion. My advice would be to not operate heavy machinery for a while.

Great advice already given. I want to add a small detail: I would have removed a few of these grass blades, because I don't like them on the mushrooms.
