I've spent the past few days working incredibly slowly on my bane drawing. I do it in like 2 minute increments in between phone calls.
The metal tubing isn't as bad as I thought it would be. Basically, all I have to do is draw uniform lines, erase the middle and use a stub around the edges to create the illusion of a cylindrical form. Again, I'm choosing to ignore all the rules of lighting. I think it looks better this way.
Ive decided that I like drawing weird mechanical things. If my proportions are a little off, it's ridiculously easy to fudge shading or add some vague shape in the mechanics and it'll still look good.
The drawing will have to be gone over again when it's done in some darker pencils. It's not as bold as I'd like.
