Seeking the best fix...

Trying to remove this reflection of myself in the doorway, in the lower left. Coming from PS I tried similar tools with terrible results, suggestions? I know, don't stand in the doorway.😐

I assume you mean the reflection of yourself, not the shadow. 

This is pretty much impossible.

Replacing the stuff in the windows, meaning the stuff in the room and the reflection, is quite easy. If you have a photo of the room.

@OldHickory30 Below, I made a selection of both the lower left glass panes using the Selection Brush tool (to limit any edits to those selected areas). Next, I added a new Pixel Layer. Then, I worked up close, switching between the Clone Brush Tool (K shortcut) and the Healing Brush Tool (J shortcut). Make sure the Context Tool bar is set to "Current Layer and Below". All this was done non-destructively on new the pixel layer, leaving your original intact. I'm not sure how much you wanted to remove, but here is an example done fairly quickly. I left the marching ants showing so you can see the original selection. You can spend more time to get the effect you want, and also play around with Layer Opacity if you want to leave a bit of the reflection in place for realism.

Very nice, especially since you were working with a screenshot. I'll give those options a a shot on my end. Thanks!
