Bert,
Not bad, but it looks like a "minimum" PS filter has been used to smooth the image, sadly this detracts from natural looking stars, which also show very little colour variation and are nearly all saturated to white.
Greg's
recent rendition is a great paradigm of what I'm alluding to here.
Also there is a significant background red cast over most of your image which you might want to work on.
Stick with it!
