I forget to measure, and it throws me off, as some people just aren't these measurements. The biggest things are knowing negative shapes. If you know your negatives shape, they will show you where you're off quicker than any measuring.
I am lazy. I can't be bothered with the dynamics, even though I drew over 9,000 houses, I never checked perspective, and even know how to 'cheat' for a better picture. If you draw a lot of things to perspective, it doesn't work. A house on top of a hill, for instance, if you draw it to perspective, it looks like it's falling off the hill.
There is a very good DVD I saw some of. I've forgotten her name for now. Watercolors NZ artist - she does floral calendars - tichbourne (nancy?) or something like that. That is one I would recommend to you.
