Bike fit help

Looks good but you want to bend your elbows just a little more, straighten your upper back, relax your shoulders… This is to prevent neck pain and putting too much weight on your arms/hands and everything bad it brings along (carpal, soreness, pins and needles, elbow pain, etc.).

You might want to check your KOPS too, my guess is your saddle is slightly too far back.

edit: you might need to adjust your saddle height too, just a tad lower, it’s hard to tell but your leg seems to be stretched on the 4th pic, back of the knee pain is not fun.
