I am new, needed to practice shading 3D shapes. So this month challenge was perfect for me to jump in

Also bit selfish, I chose to shade my name. The drawing is symbol of Infinity.
In Indian language Anant = One that does not have an end

= Infinity
So decided to give it a try.
One struggle for me is to get the dark shades, I used printer paper and getting true black appears to be a real challenge. Because of that it does not create the depth I wish to achieve. Any tips would be really appreciated.
