This drawing of one the classroom mouses I feel came out quite well. I used a mixture of 8B, 4B, 2H, H and F grade pencils, to get the desired look I wanted for the drawing. For the bottom dark part of the mouse I used an 8B to cross-hatch tightly to get it to the darkness of the actual mouse. I didn’t do this too heavy as this part wasn’t Jet Black. For the crevices I pressed down harder with the same grade pencil to get this part much darker and stand out from the rest of it.
