Hey thanks guys. I'm not too worried - I am perhaps being overly critical as I'm trying to get the best out of it as I can. I do like the image and I also think it's probably the best I've done so far.
So, it's mostly looking at ways to improve, because it's cloudy outside, I'm back in my light polluted backyard (it's like a big downer after being at the dark site :p) and I've nearly run out of other data to process.
