Some pencil sketches

I've been doing a lot of pen and ink sketching this year and thought I might return to pencil for a while.(5B Staedler)

The one below was done with a Derwent Onyx pencil (Med). As usual, I really like how it holds it sharpness throughout the whole sketch, so I can sketch quickly without having to stop and sharpen it, but it does feel like I am sketching with an HB pencil.
