Hello,
Gary, thanks a lot m8. In return I'm aiming at converting figure as good as you do (the Nordland MG part you recently published seems lace work for me). Re oils, in fact I'm not using them in the classical way. Regular way (as far as i can read from french Figurine magasine for example) is to undercoat with enamel (or even acrylic) and then use only oils by streching several layers one after the other (with several days in between for the drying), using several brushes, one by color, and without using thinner at all. In the Julian's way, I basecoat with enamels, make all the shadowing and lightning with enamels, using approaching color to the base one instead or only black or white. once the enamel job is done, I then apply different washes of oils, more or less diluted depending on the effect I want to achieve. On his right arm, I applied yellow and brown very very very diluted washes which you can guess on the pictures.For the gloves I mixed enamels and oils to give a richer/brighter texture to the green highlights.
As far as complexity in regards to acrylic, I don't know as I used acrylic only a few time, quite some time ago. I tend to think oil colors are richer and can allow more subtle work (eventhough I've seen tremendous job with acrylics, specially in fantasy figures).
Mario, thanks a lot for your comment. Highly apppreciated. The downside of doing subtle work is that sometime under the lamp it looks terrific but next morning under day light your work is barely visible..I spend a great amount of time on the garand stock to replicate wood grain. In my opinion the rendering is great, but you can only see it in daylight, and impossible to catch it with my camera... I do also take great care to blend each new layer with the previous in the highlight and shadowing process. I wait for the paint to dry a little, a few minutes, and then apply some thinner very gently to turn hard hedge into soft hedges.
Last Julian's secret

: I use flesh tone to make the final highlight. It works very well for brown and black for example.
Thanks a lot for your support and kind comments again.
Julien
