Awesome progress, Bran, love the sumptuous lips, btw! Not being an acrylic addict, but an oiler, I see what you're talking about as far as shading the left arm behind the shield, but you have handled it very well. Awesome shield work, too, and the flesh tones are coming together smoothly, great contrast, tonal variations, beautifully done.
I see Arnau's work as incredibly impressive, but that "bling" appearance is over the top for my taste as I personally prefer a more life-like natural appearance. Now that's just me, but I've noticed a lot of acrylic addicts over exaggerate tonal definitions and shadows/highlights, to almost a cartoonish appearance. They look astounding at first glance, but lose my interest by the lack of realism. I don't see your work in that vein at all, Bran, so I already know this will be superb when finished. Sorry, I just had to give you kudos, and did I mention great progress?
Ruck On!
