Bristol Hercules XVI plane engine pen drawing

Hello fellow steemit artists! Hope ya'll doing fine today. Right now, I'm drawing a very old British plane engine called "Bristol Hercules" only with a pen. As you can see, I added some parts that are not even part of the machine. Cuz, why not? This drawing's like 3 months ago tho. But still, I wanna share it to you guys.

Hope ya'll like it
