Hello....
It often happens that I have to redo a drawing, even 3-4 times, this teaches me a lot, and it is very useful to make you improve .... the drawing that you have not inserted, with excellent potentiality .. that arrow that forms a piece of the letter , I think it's fantastic ..
I go back to your main drawing, I really like how you use the lines to create the letter and also the 3d you chose .... good work;)
