Taking pictures of a mirror can be a problem.

If I take it  straight on, I get a reflection of myself in the mirror.

If I take it from an angle, I get the room reflections in it:

If I take it from an angle so it only reflects a white wall, it looks like a picture frame with a white backing or an empty frame:

I tried taking it outside so what was reflected in the mirror looked better, but then it looked like a framed picture of some flowers:

Finally, I decided it would be best to just have a plain wall reflected and a flower close to the mirror also reflected:

That seems to work rather well and also helps to give some scale as to the size of the mirror. For a large wall mirror, having an attractive young lady standing next to the mirror, smiling into it would also work well.

Oh, and for my straight on shot of the mirror, I just decided to use gradient blur in image editing, but I don't think most people would want to get into that:
