Goldfinch in Flight

Another chapter in the saga of my attempts to capture small garden birds in flight. Sadly the sequence is not totally sharp and I do not have a shot whether the wing feathers are outstretched giving the multicoloured blur.
 
I have included an extra shot of what I think is a juvenile great tit but I have never seen one as fluffy as this before and would like confirmation of its identity from the avid birders among you.
