You are welcome and thanks for asking. Digital art is not really where i specialize to be honest. But, i thought this one was really well done. The only thing that stands out to me that would add to the overall finished look of the art would be a little texture. Your shading is really well done and give the feel of dimensionality, but texture would take it one step further. I don't mean like 3D mesh and digital textures but in your details.

Like, if you had some little lines on the vines and leaves. You already have a few little lines here and there on both and that added to the contour and flow... but to add a few lines say on the edges of the leaves to give a bit more depth. Or say a few lines that are not black but varying tones of green in the hair to give the illusion of depth.

It's really really good as is and my suggestions are really just adding and tweaking minor details more than some giant overhaul. If you look into cross-hatching as a drawing technique... i think this would give you the idea or concept of what i am referring to. Not that you should use digital cross-hatching but to mimic with lines that effect. Using darker shades of the same color you are on top of would give more depth as opposed to using black. Black has a lot of contrast but has it's uses for sure.

Sorry for the long-winded answer but do keep up the great work!
