The fore sail looks a bit lacking in that normally with the see-saw boom I would try to arange a tension line at the trailling edge of the sail to help control the shape of the fore. It looks like the leading edge of the sail is held in shape just by tension applied to the sail. Again, I would normally have a line there to provide the straight line, and hang the sail off it. The lower the bottom edge of the sail to the boom, the better.
The golden rule is that the leading edge of all sails should be straight, the other edges should have a gentle curve.
Add this to andy1499's excellent advice and you should have a good 'un, and plenty of fun sailing.
