New techniques?

 I don’t like this sketch/drawing thing, but… it’s a new technique that I want to take into my normal drawing style. 

Harsh direct lines, it eliminates the sketchy lines that can sometimes be good, but for  perspective drawings I need more precise lines. 

Hopefully practice rough techniques like this, And interpreting it into drawing will help massively. This will allow me to draw quicker and with accuracy, helping present my ideas better
