Hello Guy,
well that is a very beautiful piece you did !! beautiful figure, well painted, well presented on a beautiful base, it is 100% OK; great work !
I like the skin tone, and the muted colours of the clothing, and the red-brown leather arrow case with gold decorative elements gives this piece it's subtle touch of colour - beautiful!
Your eagle also is well painted, it is indeed correct to paint the head in a somewhat lighter, golden brown, this would be especially visible on the crown and neck of the bird.
On the issue of how to paint the birds of prey that you find now and then as an accessory with figures, allow me to give you a tip : use the following colours :
you can replicate almost all the browns and greys and even blacks and whites of the plumage of birds of prey with the following three colours, which can be mixed in many, many different proportions and endless combinations :
Burnt umber - Ultramarine blue - Titanium white.
Also useful are Gold ochre and Burnt sienna (for example for the "golden" hue of an eagle's head), and of course cadmium yellow for the legs, feet and ceres (fleshy parts) around the nostrils.
kind regards,
Johan
