Here is part of the reply that I sent, and I have posted it here in the hope it can be of use to others too.

“How did I learn to paint? I just started and learned from my mistakes as I went along. It takes time, but here are the things that I have learnt from experience and things that work for me.

1. I have to be in the mood to paint. Sometimes weeks go by before I get in the right mood.

2. Don’t rush. Some of my figures took up to 100 hours to paint! But not all in one go.

3. Look at real life. For example, I guess you have a pair of jeans. What colour would you paint a figure with jeans? Blue? Wrong.
Really look at your jeans. They are actually white and blue in fine stripes. So paint a light blue base coat on your figure and then dry brush a little white on the top. This gives the two colour look that your jeans have in real life. Look at the folds in your jeans. The top of the fold is lighter than the bottom of the fold. But there is no line separating these colours. So pain a lighter blue on top of a fold. A darker blue at the bottom of the fold. Now blend with THIN washes between the two. You will get a graduation of colour from light to dark.

4. Dont paint where you don’t want paint. Silly to say, but so true for ’sharp’ colours. For example. You have a figure wih a red jacket and white belts. Don’t paint the whole figure red then try to paint the belt white on top of red. I don’t know why, but it does not work. Paint the jacket red, but carefully ‘miss’ the belt. Then paint the belt white. This will give a clearer colour and will also make a very sharp line contrast between the two colours.

5. Don’t rush – use lots of thin coats of paint instead of 1 thick coat for the main surfaces. For a jacket I would paint a number of thin coats of paint. Then a number of slightly different coloured THIN washes. Then the graduated highlights on the folds. Finally over the whole lot another VERY THIN wash of basic red. This will give you a jacket that is a myriad of different colour reds, but the eye sees just a realistic red jacket instead of a single red layer of paint.

6. There is a tendency for people to paint a really good figure. Then, for me, they spoil it because they outline in black every single detail. In real life do you see a soldier’s belt with black lines painted either side of it? No. So don’t do it. Use the technique in 4 above to get a natural sharp contrast. If you want to outline a detail to make it more visible, use ink and a 000 brush so the line is very fine and almost invisible. That works just as well as their thick lines but is far more natural.

That is probably enough to be getting on with at the moment. If you want any more help, please feel free to drop me a note and I will do what I can to assist”.
