I've had a look at the race Blue. If you freeze on 35 secs (just after the winner switched out but still behind Likely) you can see clearly the length of stride the winner has. I was drawn to it straight away without knowing it was going on to win. As regards Likely, that is more difficult as freze framimg on 56 secs (I think) it shows there is nothing wrong with her front angulation. But at one point I did see her front legs rather high off the ground. The only explanation I can think of is that either:
(a) she was not fit and not given a hard race once the winner strode past (clearly had no chance against that one). Jockey didn't exactly ride her out.
(b) she just doesn't have the power at the rear in which case if she didn't lift her front legs she would be due to hit the ground before she got her front legs ready to land. That doesn't tie in too well though with the way she won on début
Personally I think 5f is far too short for her and it might be worth giving her a chance over 7- 8f to see what happens
She is a chestnut filly
