Hi Skypacker,
Your shots look better than mine! But I would suggest you set your WB to "tungsten" for that more natural colour effect...that's what I did.
You are too kind

Reg WB, I have the RAW files, so I am going to try the different settings. I started off with a slightly warm color because I like the slight 'yellowish' light look for night photos

Maybe we can make this thread an 'official' Pentax night photos thread? What say?
