Dina I understand your concern but your piecing is fine. The problem with a lot of the 3D quilts is that they "look" a lot more 3D when you view them from a photograph or from a distance. Close up they can look just like a lot of pieced bits. You need to view them from just the "right" angle to get the full effect. I made a 3D piece that looks really odd when I place it on my bed because my rooms are too small for me to be able to stand back and get the right distance and angle to view it. However, in a photo it looks fabulous! I was quite disheartened and never totally finished the quilt....can't remember what I ended up doing with it.
