amahir:
1. when looking at your picture the eyes are drawn to the relatively bright trees at the bottom of the picture and not to the milky way which is the subject matter.. silau.. so crop the picture to remove them but if trees are part of your picture then darken it by using the burn tool so as not to compete with your milky way.
2. Your sky is too red RGB:39,25,16. Suggest the sky shall be 30,30,30. Try not to make the sky black at 0,0,0. Too artificial
3. So I reset the black point, increase the contrast and brightness , balance the colour , saturate the colour and a bit of noise reduction and sky at 30,30,30

or a brighter sky 48,48,48
