I'd originally planned on using the painters that we've had doing our website photos (JAD, Kev Rouse, Matt J) but I'll bear your offer in mind. Were you thinking a full tutorial on your methods or more of a list of advice and suggestions?
My painting's not of the standard to do a Dallimore "Painting by numbers" with pictures.
When I've done these in the past, It's been a checklist of things, which if got right will enhance the overall look of the painters work.
It won't turn anybody into Michelangelo, but gets good results from my own limited ability.
My own view is that only about 20% of the effort consists of daubing the paint onto the figures.
This is particularly true of the smaller scales where preparation pays great dividends later in the process.
* Inspecting the figures, cleanup, and sanding the underside of the bases.
* Sorting the figures by pose then grouping them into unit sized batches.
* Sticking them onto painting sticks.
Then there's the artwork of painting, followed by
* Basing.
* Texturing the bases.
* Sealing / varnishing.
I'm sure one of your regulars could bookend the painting guides with these steps.
