Your knee appears to be still bent when the pedal is in the down position. That bike is too small for you.
Hard to judge completely, as your pic is not in the full down position, so I am guessing a little.
I use this guide for vintage bikes. I find it pretty accurate. Modern bikes have different geometry where the guide is less accurate.
