This looks very realistic.

I've seen Northern Lights about 4-5 times now; once on the ground in
Anchorage AK, once in the air, and twice in Upstate NY (dark skies).

Generally speaking, they are pale bands of color.  They don't show quite the
same way pictures do - I've often thought it's because the exposure has to
be timed to get it all, and as a result the pictures look more 'wavy' and
brighter in certain areas as the colors overlap.

So if I made any change, I'd make them fatter and don't overlap them too
much.

If you animate them however, you should know that they can 'rope' all over
the sky.  I never saw them fold over themselves much.

Interested in other's impressions though, it's been probably 25 years since
I saw the ones in Anchorage; the ones in Upstate NY were just 3 years ago
but were far less bright.  (which is odd, you're closer to the magnetic pole
in NY than in AK).
