some drawings of mushrooms and gourds

I made some drawings of mushrooms and gourds this week.
The gourds are drawn on cartridgepaper and hb and 2b pencils
For the mushrooms I used charcoal and grey and white chalks
The first mushroom is in real 4 cm and the drawing is approx 26 cm. So a huge mushroom.
But when you work with charcoal you cannot work too tiny.
The drawings of the other mushrooms are also very large.
