Today I found the best tool in Photoshop. It only took me about 6 years, and it's the navigator.
I've known about it for ages, and I just found it annoying and in the way of my workspace. It's unreal the difference having a thumbnail in real time to look at can make. I would have been fairly vigilant in zooming in and out to keep an eye on overall composition (someting drilled in in lifedrawing) but it doesn't compare to the navigator. Use it if you're painting images in PS.. its vital !

So hopefully my next images will show this improvement
