The exact estimate will depend, as I said, on wind direction (pure head/tail wind, or quartering headwind out, quartering tailwind back) and the tires/tubes/road surface but let's ignore those things and say .26 m^2 is right. Are you extremely tall? If not, I'd say .26 m^2 is good but not great, and you have some room to improve. That H3 is quite good when used with with a narrow tire and in pure head/tail wind conditions but less so at non-zero yaw, or when used with a medium width (like, 23mm) tire.
I guess maybe posting pictures from the side and front in an Aero position?
The eyeball isn't a very precise estimator of CdA, but it can often be useful in making suggestions about what to do next.
