Not sure about nicely done , but thank you ...no experiment I am new to the hobby and while I prefer oils its really tough with so many people saying so many things I have painted a few other bits but this is the first one I posted................I usually do the following..
Prime some times in black but usually grey
Then a base coat acrylic usually a sand colour
I then mix my oils and apply a layer of the particular skin tone I am trying to get and then thin it back
My next effort is usually where I get it wrong , in that I dont do enough to to make a good contrast so while I know more or less where to put the highs and lows perhaps not enough difference in the skin tones
Eyes ,lower and upper eye lids in acrylic and the rest in oils
Uniforms ............maybe too much paint I dont usually thin it and of course am poor at shading so feel free to add your thoughts have sent you one of my other bits
