Wow! Awesome artwork and really fitting title too. The "Stormcrow" nickname always seems to emphasize Gandalf's more mysterious and dangerous (but not malevolent) side, which this picture does too (again without making him seem at all bad--just a bit tricky and shadowy).
I love the atmosphere you created with the textured effect and different color on the linework, although it has textured and almost flat colors in some parts, it creates a very natural effect, with the focus point on the face (which is beautifully rendered). Wonderful!
