Your rearrangement of the seating is a huge improvement. For balance, you really need a longer couch instead of that dinky loveseat. Depending on budget, I'd keep the two black chairs (if they're Ikea's Poang chairs, I know they're comfortable) because they're neutral and allow great flexibility. When you do a gallery wall, don't use those frames with multiple openings for snapshots or anything like that cluster you have now. Choose your very best candid shots; remember, this is your artwork so it should be compelling. You can create a cohesive gallery wall by framing all the photos the same, or by converting them all to black and white or sepia tone. It's pretty inexpensive now to have them printed on canvas and stretched. One of my favorite uses of family photos is this:There are some articles on Houzz about creating gallery walls. The trick is to keep your grouping tight, to vary the sizes and orientations of frames, and to arrange them in a way that creates balance and movement. Houzz doesn't seem to be working right now. I'm going to quit my browser and return.

My advice would be to go on Houzz and start some idea books to figure what your style is . Right now all you will get is dozens of ideas that will keep you more confused than ever. We need info to help with this.

Sigh.. I have no idea what I'm doing wrong, but every time I try to reply, I lose the response. Hopefully 3rd time's the charm! Let me summarize even further now that it's my 3rd attempt - Thank you @Patricia Colwell!! I appreciate your response. I agree it is definitely a very formal set, and I'm not sure if I could fit it with the rest of the house, given I intend to have a more "casual" or "relaxed" feel in the adjoining rooms. I love the look of formal sets, but the rest of the house would be very informal. I'm not sure eclectic is the exact match, but I said that because I've been going through interior design photos the past few weeks, and all the ones I'm drawn towards have all been labeled "eclectic". I have 0 eye for design, though, so I would not go down the eclectic route, as I would definitely hit "tacky and bold" as you mention. Maybe my style is more transitional, but with a bolder color palette and a few older-style pieces, like antique-looking armchairs? I haven't pinpointed the common theme in what I like yet, but the "eclectic" (or whatever they really are) homes feel more "homey" to me, whereas modern just feels too staged for me personally. Looking through more pictures, I really like the legs in this set and the comfiness of the chairs, but I don't like the drapes, painting, or chair fabric/pattern - And I think the tables in these look really interesting, but I'm not a huge fan of anything else in the rooms -

The actual reflection in the furniture is a non-issue for me; by the time everyone is seated, lights are adjusted, I don’t think that much will be visible. If I just loved the 2 pieces I’d look for ways to pull my vision together. maybe some simple contemporary mirrored candlesticks or other streamlined bling would be a starting point. I’d try to choose pieces carefully and not vary far to insure everything works towards the goal.
