Here's the stained-glass piece I ordered:

Meyda 24"x11" Tulips Transom Stained Glass Window · More Info

Here's the window where it will be hung (the valence will be going away):

Here's a light fixture I'm considering:

Chloe Lighting Theros Tiffany-Style 2-Light Semi-Flush Ceiling Fixture 14" Shade · More Info

Here's the current "boob light". I don't hate it, but I don't love it.

My concern is whether the light I'm considering would coordinate well or be "too much" for the space (it's a small bathroom for a master bath, and there is a door between the toilet/tub portion and the sink portion), given that I'll already be doing the Tiffany-style thing with the window. If a pretty fixture would fight with the window hanging as a focal point, I might be inclined to keep the "boob light" (which, as boob lights go, is not so bad). Also, I'm wondering if it would be bright enough for my hubby's liking (he doesn't really like to make decor decisions, but he did say that he thought my stained-glass piece might darken the room a bit much, although I think that it will brighten things up compared to the current curtains). Given what I know of my husband's preference for a well-lighted space, I don't want to double-down on anything that he considers dimming. A light-green shade of paint may brighten things up from the current shade of grey. Thoughts on lamp and/or shade of green?

So here's the stained-glass piece in situ. A lot of what looked very peach-colored in the photo I posted previously is a lot more pink, but I still like it. My mom, who has impeccable taste, agrees with me on the light green for the walls. Just need to decide on the specific shade.

Maybe something like BM Green Cove Springs? Anyone willing to help with a mockup?
