I'm afraid it looks a little too low in front to me, not a surprise given the CC-type panel and your horse's slightly pronounced shoulder. Sliding back is another sign. It's often not a tree width problem but a panel adjust problem.
It's possible he feels free because of the reduced support in front (saddle's less restrictive). Unfortunately this puts more pressure at the base of the withers, which usually takes longer to show up.
If the saddle was properly levelled you'd probably improve your balance in it, even out the pressure and stop it going back. The rear panel makes average contact (another CC problem - no gussets) because the tree's slightly too curved, but unless you're a heavyweight I doubt it's a too much of a problem.
You could try a folded towel at the front to experiment with level, but CC panels are awkward to adjust effectively unless flocked, which I doubt this is.
One thing not visible in your pics is side-to-side level. You can quickly get an idea by measuring with your fingers between wither and inside of front arch (above the panel). The measurement itself is not particularly important, just that it's similar both sides of the horse :)
