Fedodika the Koala

[darktiste]

I think you should separate your study in category for example reflective vs none reflective// transparent vs opaque that absorb light you can than compare and adjust the element to reflect how those thing really behave if you study all in one you might miss the point and just copy and not think about the reflectivty of the surface.When you pratice get rid of the complexity and go straight into the concept to distill it down.For example instead of drawing a full armor try to draw a cube made out of metal if you can draw a cube made of a material you can pretty much apply the concept you learn to a more complex object.

For a quick run down of what i did on my critic of the last piece.
I choose to desaturate the color and increase the contrast.
I Think you might want to introduce abit of green in the face and hair but not to much since feather are not that much reflective.
