I've got more than I have have before but I'm stuck.
Theres a reddish round circle on the left which I can't get?
And also another green circle with a yellow/traiangular shape that I don't recognise (above Hotel meister Palace)? Any ideas?

Blue Circles are "Only Connect".

We're stuck on the yellow flower just below the X Factor sign and to the left slightly. Any ideas?!

We're stuck on the little yellow flower underneath the X Factor sign - anyone got any ideas?!

Could the yellow flower be 'Flowers' which starred Olivia Colman which aired on Channel 4 in April 2016? If it is a clue though I'm baffled as I already have 50 answers without that one?!?!
