Looks like a very relaxed position with plenty of stand-over room. You could slide the seat up a tad.

What is the bike brand and model? What does the manufacturer say about your height and bike size “for that model?” 50cm frame size alone doesn’t tell you much about the bikes frame other than the seat tube length.

First, please note that the only useful pictures to answer your question are ones with the pedal at the bottom of the stroke, and taken straight from the side. You can hold on to a wall or tree without the bike moving for them.

It appears that the saddle is 2 to 4 cm too low for you; your knee should be not quite straight at the bottom of the pedal stroke.
