Hey there Andy!
Just dropping in to say that I really love your sketchbook (perspective enviros are great!) haha... and maybe offer some feedback..hope ya don't mind!
Those foreshortened life drawings really reminded me of harold speed's drawings in his book "The practice and science of drawing" so I thought I'd say a bit about them. You also seem to be approaching drawing in pure line as he does as opposed to tone/mass drawing. I would suggest reading that book! It really is a goldmine of knowledge. Anyway he goes into the details of how line affects a drawing....drawing lines across a form gives the illusion of softness, lines down the form gives the illusion of hardness and tension, curved lines give the illusion of fullness of form and lines drawn in many directions so that mystery of tone results gives the feeling of atmosphere. You can read more about that(better than i can explain) for free here (no copyright) Or you can get a copy too which i recommend, great for quick reference.
Here's the drawing that I was reminded of:
Also I thought I'd comment a bit on the akira environment ( Otomo is awesome ) Your perspective line work is really really good, but I think the colours could be improved. I think there's too much use of black. Everything feels a little disjointed as if they aren't affected by the same light. Also with neon lights that strong, I would think there would be a greater colour cast onto the surrounding area. (M@. is awesome at describing those lighting situations, something I'm still figuring out too.) hmm..I think a part of it too is the lack of temperature and hue shifts in your painting. The red neons for example, shifting the temperature to something warmer like an orange towards the middle and then an even lighter streak of desaturated red would give that glowy feel......like a lightsaber or something haha. Even shifting the temperature on the walls as they get closer to the ground( reflection of the ground/dirt etc) can help.
Also, forcing that atmospheric perspective would tie the piece together a little better.
Here's a Craig Mullins piece i took and supeeer saturated.
You can clearly see the distinct planes of hue changes from foreground to background RED > GREEN > BLUE. Objects receding in the same plane in space tend to have the same colour cast... no idea if Craig does this consciously or not but man is he good TT_TT haha.
Erm yea hope that makes sense or helps heheh...I'm terrible at putting my thoughts down into words. And I hope you don't mind the attachments disrupting the flow of your SB. I'll take 'em down if you do mind
EDIT: Darn I topped a page -_- haha
