Some of the WB are off tbh but not too bad! Clart has the right idea!
I'm intrigued as you said this about my fireworks pics (which to me looked 90% as I saw it), which ones in particular look 'off'? Also which WB settings would you suggest for long exposure night shots?
Most things are bathed in different types and colours of light due to the various different street lighting used around the country/world. My pic above for example, might look strange having a yellow tint to the boats, but that's how they looked.
I particuarly like Ballsie's trails, the colour in the sky and around the signs, trees etc is fantastic.
