Your WTSD% seems to be the main potential leak in those stats.

Obviously we shouldn't be striving for certain numbers but just trying to play good poker but it is interesting that you are near the optimal 'sweet spot' in all your numbers except WTSD% & consequently W$SD%.

Having said that your button strategy seems pretty good.
I would just check that all the hands you open on the button are profitable for you. (For e.g. I can't play anything more than +- the top 45-50% profitably but I seem some people opening 70%+ from here.)
