Mustang

This came galloping on a lonely Photoshop blank canvas in a few seconds.

It's not good, it's not accurate, it's just a few brush strokes. But it's fast and spontaneous and I think this kind of random outbursts can give out a lot about our inclinations and what we need to improve on.
Analysis!

• More dynamic and fresh than my usual stuff
• Values seem decent for a very loose sketch
• Took very little time

• Anatomy is off here and there. I wanted to keep this one as it came out, but if I were to pick up from here I should really grab some references and fix neck, legs and whatnot

Experience gained: 4 points! 

- I should start doing (very)speed sketching from reference and concentrate on communicating values with just a few quick spots of color. This should boost my skill with perspective, volumes and synthesis
- When planning an illustration I should let loose more often and produce a wide arrange of spontaneous dynamic sketches, hoping to be able to keep everythng fresh while progressing...
- ...then prepare a nice set of reference pics and fix what doesn't work
- Using a heavily texturized brush helps keeping some elements out of control and favors happy accidents
