Your comments definitely are more unique and specific to the post than most I reply, however you still use these same phrases I look for, sometimes commenting only, "Nice photos" or "looks great!" Also, the machine learning implemented by the Sincerity API also calculates your spam score at 64.9% which is a further indication you may be falling short.
Your remarks are primarily complimentary and that can be conveyed with an upvote alone as continually making comments for the sake of comments impacts bandwidth and harms the blockchain.
