First of all, putting a dry fly in a glass to see if it floats is not a good test. Test your flies on the stream tied to a tippet.
Second, the design of your fly is such that the entire thorax will be under the surface near vertical and the hackle will be left to support the fly.
Third, it looks as if your hackle is not dry fly quality. Without actuall seeing it, I cannot tell for sure. If you look at the pic above of the parachute adams that nfrechet tied, you can see that the hackle fibers stand straight out and appear to be stiff, and also the hackle is tied in very densely. You hackle is bent on the ends and appear to be softer, plus it is not very dense.
Fourth, the CDC wing is not very dense either and will add very little buoyancy to the fly
I would check your hackle, tie it denser and maybe even rethink the pattern design.
Good luck.
