I worked with pheasants on a larger scale. I use to work for the IL DNR at a Game Propagation Farm where we raised in excess of 40,000 pheasants for breeding stock and state hunting preserves. We had approximately 1000-1500 pheasants per pen with (40) 1-acre pens that were fully enclosed with a hot wire. The pheasants really needs some cover in the pens, so we allowed the Giant Ragweed to grow to about 6-7' tall then we would send a crew into the pen and break the ragweed off to keep it from getting too tall. This provided both shade and cover.
We had to put blinders on the chicks, and kept them in heated brooding houses until they were old enough to go outside. But they kept the blinders on until the day they were going to be shipped out. We expected casualties from the pheasants flushing and flying into post, or hawk and owls flushing the birds and grabbing them through the netting. I would definitely add a hot wire around the base, keep them partially shaded, and protect them from overhead predators.
View attachment 1274735View attachment 1274737 Pen looks great except a little small for pheasants.Are you looking to get ringnecks?If so,way too small,they need lots of room and cover as they are cannibals.Goldens or amherst would fit a little better then ringnecks,but no more then a pair.i do not see a cover on your pen.It to needs to be covered,I would put a pitch on it like a house so rain and snow will roll off.Either in wood or metel.I suggest metal as it will last longer.They also need a perch as the branches you have are rather small and now very level.A 2x3 or 2x4 about 2' down from the top.I do not feed on the ground either.I use rubber bowls from tractor supply for food,grit and water.

I agree with @Tony K T and @pintail_drake2004. Covering the top with metal roofing would be best...also, you will want to put an apron around the entire enclosure, to keep predators from digging underneath the pen.
Small shrubs, fountain grass, a few large smooth rocks, maybe a stump or two, a couple of perches at different heights (pheasant furniture) would add greatly to a interesting habitat for your birds. It will also help prevent "pacing" the perimeter of the enclosure.
As stated, it is too small for ring necked pheasants. Ring necked pheasants are more ground oriniated, they don't use perches as much as Goldens. A pair of Goldens or Amherst would do ok but with pheasants, larger is better. Would make a great quail pen for maybe 10 -12 birds. HTH
