Sketch on toned paper

Here is a portrait sketch from yesterdays evening. I've used A5 toned paper, B2 pencil and white pastel pencil. I know it looks sketchy and messy a lot, but I like the form and a real/3D look/feel (finally). I hope this could be my way... :)

Weekend sketch

This is my new weekend sketch done with KOH-I-NOOR black pencil "NEGRO". A4, 1 hour ish...
Used some picture from my favourite book about chiaroscuro as a reference..
