Sergio, This is a cracking set of mirrors, well turned in each discipline, flat work and spindle, you've got an array of fine details to the pieces, do like them.
It maybe picky in saying, yet fair in C&C as asked, two of the mirrors I can just detect minor flaws, slight ring marks to the back of the spalted beech, sanding or in the finish not to sure which, and tear out to the top side of the upper bead of it's handle, shows in bottom picture the most, it's more the half cove cut was not completed, than to the bead.
The other is again to the back of the dark mirror (2nd pic) with a couple points of tear out in the grain (3 o'clock) and slight undulation to the surface.
These will grace any dressing table and become treasured heirlooms to whoever receives one. Well done, keep the excellent work coming, thank you for sharing.
Cheers David
