Your seat is already far enough forward. It is already far-forward positioned similar to a triathlon/TT bike.

Your seat looks like it's set way too low. In your photos your knee doesn't look like it can get to that 30-degree extension at the bottom of your pedaling stroke.

Get your seat to the proper height, then determine what stem you will need to get to your preferred upper-body riding posture (how much stretch you prefer, and if you like more upright or less upright).
