I think it looks good, but you need more pad. The blanket should be scooted up, so it's equal in front and back, and you need a liner pad to go underneath. Western saddles with synthetic fleece are NOT made to be used without some kind of good pad underneath. Blankets are fine, and fun
, but you should have at least a 1/2" felt pad under your blanket, to give your horse some cushion.
I would move the saddle back about 2", to free up his shoulders. He seems a bit tense in his neck, and you can see the saddle is up over his shoulder blades while he's standing still. That will make him uncomfortable at faster gaits, when his shoulder move back and hit the tree.
