*Reuploaded after erasing dirty background + added a frame*

It's not exactly perfect but... So far my best piece ever. Shame it ended up being a tiger/lion hybrid. And its facial expression was meant to be RAWR not 'Whyyy meeee, buhuhu?'. Oh well, can't have it all.

TOOLS
2B pencil
8B pure graphite
Finish: Carbon
Adobe Photoshop CS6: light background cleaning (no other adjustments!)

CRITIQUE WELCOME. I know some parts are drawn incorrectly and I would like to know what to pay more attention to and how to avoid mistakes.
