I quite like the idea of priming with the base uniform colour as a principle, especially if there is a lot of that uniform, so priming `Austrians White and Confederates grey is brilliant.
Once primed, I apply a heavy coat of ink and then go back in and rescue the the highlights of the primer colour (in this case blue).
The block paint that follows needs to kill all of the surplus primer (blue).
The choice of shading is an individual decision, at this stage, I would tend to selectively ink parts of the figure and then go back in with a fast highlight.
You have chosen to poly dip, and the two problems as I see it is that the dip went on too thickly and has 'dirtied' the figure too much and the dip tends to 'bronze' some colours ….. blue being one such colour.
I am also guessing that in your efforts to get the excess dip off, you have also taken away some of the block painting, to reveal blue primer.
I think the process is worth staying with for 'speed painting' and that the technique perhaps needs tweaking rather than abandoning.
I know some people put KLEAR on their figure before inking / dipping to reduce the effect of dips sticking to high areas (caused by the excellent tooth that acrylics offer!)
good post and thanks for sharing, I think this sort of thing really helps gamers.
