Oh, big thanks for the links! I'll check all this stuff out, great.
I was tinkering with the lights again today, and actually realized the direction of the lamp is much more crucial to painting than I previously realized (duh!). I managed to improve my painting light condition considerably just by positioning the light so that it points as much to the direction I'm painting into, as opposed to just having the light above the model. But I am sure that things could be improved even further by investing into a better lighting system.
Another nice surpise was testing out AK weathering pencils I impulse bought this spring. While not exactly a substitute for proper multilayer edge highlight, the control of a pencil compared to a brush is superb and allows me to dial in at least a passable semblance of an edge highlight. They also work quite nicely as a drybrushing alternative for working on small areas like armour joints etc, and work especially well for base texture higlighting.
And yes, Terrain is wonderful to work on, but I got so much on my backlog/pile of shame that I have to tackle some of my new models as well. I think I can still reach a passable "tabletop" quality, so its also a matter of adjusting my expectations.. Not going to be winning golden demons suffering from retinopathy etc, and coolminiornot 9/10 tier was always beyond my reach anyways!
EDIT: 3800 lux eh? That's more than double what the 1500S outputs. I think we might have a winner.. Just have to make sure the dimensions aren't too big for my workspace. Great stuff!
