Nice studies so far! I would also suggest switching to blank paper, even though you say nice paper would make you want to draw something more "pretty".. I'm sure there are crappy blank paper pads out there.. you could always try printer paper, that's a devil to draw on. Or letter paper! XD
Apart from that, keep up the practice, maybe go for more detail in some places!
Insanity is the key! Also, studies are a key. And passion is a key. Also, so are inspiration, motivation and dedication. Talent can be a key. Insomnia can also be a key, depression is a sad rusty little key. Damn, artists need one hell of a keyring.
Nope! Gonna stick with the lined notebook and torture all my viewers! (At least until this notebook runs out. . .)
Detail's tough with the quick rough sketch mode. For me, it takes about a half-hour to produce a reasonably good "figure" without any real background: about 15 minutes of drawing and restating/correcting, then about 15 minutes of rendering and tweaking values. (Given an hour and a half of focus, I can start to produce things that start to take on a professional gloss).
Here, I'm trying to set multiple figures into some sort of composition (usually) and rough in some sort of indication of an "environment" within about 20 minutes-- detail kinda falls by the wayside!
Part of my evil plan: by overloading my brain with these 10 to 20 minute dailys, I hope to get faster in "life drawing," where, for my source, the poses generally only last 20 or 25 minutes at the longest.
