Sorry,
@DrumDoug, it's not you, it's the drums. That frown would turn upside-down if you spent many more thousands on a silver sparkle set! Or a bespoke handcrafted set with a hand rubbed oil finish.

I'm sure there are folks here on DW who are just champing at the bit to offer their help.
All kidding aside, I wouldn't worry about it. Folks who know you, know your demeanor and everybody else's opinion (or photo) doesn't matter. The audience came to listen to music, not ogle the drummer - unless of course, the drummer is an actual Adonis or Aphrodite, in which case ogling would be warranted.
In these days of excessive cell phone pictures, Mrs Smoke remarked, "Why are you always crabby in your pictures?" Sure enough! I look like an old curmudgeon in almost every picture in her phone. (in days gone by,
I was the one taking pictures, so I wasn't present in most photos) I'm not generally a crabby adze, but even when I know I was obviously happy in her phone photos, I look like an ornery bear. Oh well...
So, take it with a grain of salt. You're not alone. And that should make you smile!
