I dunno, but seat height looks ok to me, though besides there not being a shot of you at the bottom of the stroke, the jeans make it difficult to determine knee angle. I'd bet you're quite close to being in optimal range.
What are your goals with riding this bike, by which I mean, are you planning on just doing casual rides around town, or are you looking to get out, ride hard and for some distance? How you'd like to use it informs how to tackle the comfort/fit question.
The first thing I thought when I saw the pictures was that the big looks pretty big for you, as manifested by the extremely short seat post extension, and with the main effect being to position the handlebars quite high, apparently above the seat level, even.
I think that when someone is sitting so squarely on the saddle, in a more or less completely upright position, that it is essentially uncomfortable for most riders, and particularly over time. Additionally, when the bars are at such a reach that your arm angle prevents the rider from being able to comfortably bend their elbows and basically lean their shoulders forward, the likeliness of discomfort goes up as well.
So two things, dependent on riding style: 1. if casual riding, you could swap on a shorter stem with more rise, and bring the bars in closer and higher, or 2. if more sports riding, lower the bars by flipping the stem to angle downwards and/or removing spacers under the stem to get them lower yet.
It may sound counter-conventional, but leaning forward can actually be more comfortable for some. Whether you're one of those people it's impossible to say with what we know here, but I wanted to put out the option.
If you do try going lower in the front, you may need to adjust seat fore/aft positioning, and I'd guess maybe sliding it back a few millimeters to allow your pelvis to tip forward so that your back flattens, rather than hunching over the upper back, which would be bad.
Let us know what you try and how it goes.
