Quick sketch I just made for fun. There's something cool about dirty rough sketching... feels expressive without being detailed, dunno... :D
I always recommend drawing fast little things like this if you like drawing but get tired or burnt spending hours on a single thing. Like this you can get done with it quickly and move on, maybe even have energy to draw more fast things right away. It's also great if you're trying to improve... drawing a lot of fast things like this helps you improve your anatomy, proportions and angle skills really really quick. Spend 15-20 minutes on a sketch max and call it done. :) Great training for starting on art.
