Hi Indy,
Sometimes its good to accept your achievement and put the figure in your displaycase and enjoy it instead of stripping it. If you are not satisfied with the outcome just start a new figure and apply the lessons learnt.
From your picture it would appear that painting the pturges gives you some difficulty.
Pturges are of course as in the case of the Legatus strips of leather with a protective function but they are part of the overall clothing/armour.
I would treat them as such. Before painting it therefore pays to decide which strips in general catch more light then others and which catch less light then others.
For example the 2 or 3 strips that are right on top of the shoulders catch most of the light. The ones that fall down from the top of the shoulder towards the edges of the breast plate are darker.
The top of the upper ring of pturges around the waist catch more light then the ones below and the the strips on top of the right leg would also be lighter. That is how I would see it.
In order to realize that lightfall effect on your figure I would suggest mixing 3 (maybe even 4) different basic colours for the pturges ranging from very light, a darker basic coulour and a even darker hue.
These basic colours form the starting point for the shading and highlighting of every individual leather strip.
In the picture you can see that the waist strips between the legs flow and follow the underlying form. This means that every strips has a part that catches more light and a part that sould be darker. And the starting point for highlighting and shading should be the basis mix
The contrast between the basis mixes should be obvious.
I attached a pic of a 54 mm Legatus Legionis I did myself. Hopefully they show that I do have a point!
Good luck
Paul
