The combination of fluid movements through the pyramid really generates a dynamic and energetic finish, @benja ! Really like how you vary the line weighting for the pyramid's outline too, it makes the solid shapes feels more solid and by contrast, implies that the flowing shapes to be more flowy :D
Cool picture !
@veryspider, The outline did the trick, I think. It initially wasn't there, but I felt something was missing; something that would combine the fluid shapes and the pyramid together.
