It might be both WB and exposure banding. Sometimes adjusting the exposure of individual photos is not enough to make colors the same as the neighboring photo. I use auto WB. Maybe I should have tried manual. Manual exposure is also possible, but then it will be impossible to do HDR, unless I use a tripod and have a lot of time.
Impressive editing! Best regards from Athens
