Anatomy study: 1

So...I had this drawing lying around in a sketchbook where I've all my anatomy studies there. And it has been there since two years ago and didn't even post it!!! I drew this back in 2009 - the time when I got a taste of what it was like to draw anatomy and I got hooked.
By the way, I haven't drawn a ribcage before, so excuse me if it looks shitty.

The inspiration for this came from Leonardo da Vinci. Him and his studies are amazing!

And yes, I'm cursed with bad handwriting. You're not meant to read them anyway as this is a personal study. Only I can read em' ...(actually I lied. I can't even read my own handwriting ).

This is a self-study as school taught me NOTHING. The teachers back at high school once told me that they didn't have the time to teach the students to do anatomy session. So I had to take it with grain of salt and did the study myself.
Thank you for that. Now, I am not relying on the school anyway.

This is a study for me to observe and understand how a ribcage really looks like. I need to draw more to grasp the fundamental of it!!

Drawn with ref. and it's on Google.

More boring art coming your way!
