John,
with all due respect, I'm going to suggest what I honestly consider to be the best way to answer that question for yourself... and this suggestion has 2 parts...
I've done some design work in the past, where I've asked for advice from the pros I look up to, and sometimes ya don't get much... sometimes ya get lucky a read a few comments... sometimes you really hit the jackpot & have these guys laying hundreds of dollars of design time at your feet...
when that happens, at least for me, when that has happened, I know that this was done to TEACH me, because I said I wanted to learn... so when I would start with something like you started with & someone posts something like Neato did... what's my next move? posting more questions? asking these designers to explain their contributions? NO!! ...I go to the drawing board, I try to build my own versions of their ideas... and when I have that done, if i have questions about how it works in black and white? ..I draw it in black and white, see what happens... fix anything I don't like by experimenting.. these guys are showing you the way... not delivering you to your destination...
go draw up something & then come back.. show everyone what you can do with the knowledge, make an effort to answer your own questions first, and show us that... before this thread is over, the lessons you put in practice & come back showing your results, will end up being lessons where other people learn from you! I KNOW this to be true!! I've done just what I'm suggesting, AND I've seen it dozens of times... if you just ask questions, you will get help, but it will do X amount of good, and the thread will die in Y amount of time... BUT, if you go and draw more, and come back with drawings, showing that you are using this valuable information... guaranteed, you will get 10X amount of good, and the thread will continue 2X to 3X times as long...
