I draw best when... I'm stoned out of my mind, manggg.
.. Nono, I'm kidding. :x
I draw best when I'm alone with music going in the background. It's not always relaxing music, either. Sometimes I respond best to hard, thumping bass lines, or manic jazz.
I also draw best when I've got my favrit snacks and drinks within reach.
I draw best when I've got music playing giving me ideas. That's why I never draw good while I'm doodling in class~ D;
I draw best when I have freedom n-nU And usually when I don't get paid. I like to start the drawing just because I feel like, not because I have someone asking me to do that.
So sorry for commisioners >-<
Also, I draw better random characters than my own one.
I draw best when I'm not under pressure. (one of the main reasons I've stopped taking commissions altogether) ;__;
I'm always to worried about whether the commissioner will be pleased, and what they'll think of me when I'm done. I'm more relaxed if I do things for myself, or if I'm drawing surprise giftart for people.
I know I probably seem weird, 'cause a lot of people mentioned that stress brings out the best in their art.
I draw best under two conditions[either will work]: either I'm...
inspiration hits me at 3:35 every night. i have no clue why. :/
I draw best when I'm bored. For instance, school. 95% of my dA submissions were drawn entirely in school. xD
I draw best when I'm half asleep. I don't know why. But if I'm about to keel over I can draw some awesome stuff.
I draw best on the edges of my homework. D: And then I'm like 'omg nooooo! How can I turn this in now? This is the best drawing I've ever done!' xD Sad but true
I draw best when I'm working all at once, that means...ART WEEKEND 8D. Or day or whatever context it applies to. I draw best when I'm passionate about what I'm drawing. That means I either really like the concept, the piece, or I'm doing it for someone else as a gift. c:
I draw best when I'm listening to music or when I am inspired by something like a strong emotion.
I usually draw best when I'm excited about art. This tends to happen when I'm looking through a gallery of someone I really admire, like Jubilations.

I draw best when it's late at night (like 2 or 3am till 6am), or I like the character design of whatever I'm drawing.
I draw best when I'm using really horrible materials (such as binder paper and a cruddy pencil) right in the middle of a huge exam.
No joke.
I draw best before I go to sleep. :x
when I'm drawing for myself, because it means I get full reign over EVERYTHING. often I draw best when I'm listening to music as well.
Likewise. I love to draw at night because of this. I'm not able to see so I have to be extra careful and it leads to extremely great art you guys'll never see c: Also I'm less picky because my mind wants sleep =u=
