Quick concept

Was looking at how Kekai Kotaki does his initial concepts straight from head. He pretty much does quick, inaccurate greyscale sketches in photoshop that look like random blotches on paper. But they work! At least, to get ideas out of your mind quickly. Here's an example;

Sketches by Kekai Kotaki.

This was my go, done in about 5 mins. It's really weird working quickly and inaccurately, I'm used to spending 30 hours + on any digital sketch/painting I do.

I actually hate looking at this, it's shit, but it serves its purpose in preserving my idea quickly I suppose. Already from comparing the two I see I need to be more confident with blacker lines and stop relying on lower opacity to hide my errors. Might do some quick idea sketches with charcoal to get me out of the habit.
