Make sure you get the leading edge well rounded.
Good eye, that could use some more work. There is a LE carving template in the kit, it should be AT LEAST as blunt as that. If you lost it, use the plans to make a new one. With a Fox, you are going to need that wing to work as well as it possibly can. Making it more blunt also reduces the criticality of getting it exactly symmetrical.
BTW, reviewing the plans, I would mildly disagree with Mikey's recommendation of a knife and sanding block to shape the LE. If you have one, a razor plane or block plane will be a lot easier to control and keep the LE straight. I use the little Master Airscrew plane, or a very small wooden Japanese block plane. I do the majority of the shaping with the plane, taking a series of flat cuts, then just merge them with the sanding block. That will keep you from scooping it out in the middle. Put tape across the ribs just behind it to warn you when you are getting too close.
