That marble effect is very good, just not easy to see in the picture. Maybe there should be some more contrast between body-tunica-marble. As I see it's a very fluid transition, so it's difficult to tell the parts apart.
For me especially marmor and body have the same "colour warmth" (? is that a correct art term ?

). The eagle (which is painted great!) in contrast has very dark colours that separate him from the figure and puts him into viewers focus... I'm not sure what Zeus is holding in his hand, as it's missing. So there is one important part missing.
All this is just my humble opinion, okay?!! Don't beat me!

It could be your intention to do so as it is now!
I have to finish my entry this week. Already made out a date with my friend to get it photographed on saturday, as it's the only time she has time in July. This will be a stressful week, maybe my first night time painting session. Got to get some bottles of red bull.
Here's what I'm right now. Tried the vallejo water effects "Azul Pacifico" (I'm a vallejo addict....si! ..caramba!). The consistency is great for making waves, while the colour is not my cup of tea. It will get transparent, but it's too colourful for my taste. I have some other water effects ready for use, maybe I'll need them to get that idea I have in my head into reality. So far....not even close.
So much more work to do ....
