| I think the mounts look great, quite naturalistic. As you may or may not know, mounted orchids usually do better with higher humidity, around the 70-80% range depending on the orchid. This reduces water loss through the leaves. Most of us don't have humidity that high which is why we use a bit of sphagnum moss around the roots of our mounted orchids. If your humidity is good your new mounts will be fine as they are with the roots bare, if your humidity is lower you might want to consider adding a layer of medium over the roots.
I believe your mounts will make quite an attractive display when your orchids start to flower! I'm looking forward to seeing that!
