We don't expose seatpost for a look. If you're used to seeing more on other people's bikes, you're comparing a useless metric. You say it works fairly well.

I see you have spacers above your stem. Put them under it and see how that feels. I know you're looking to decrease reach and not gain height, but this is a cheap fix, so try it next.

Also, some deadlifts and pushups can help your tolerance for the posture on the bike.
