Fun fact -- the odd sinus trouble I get isn't actually a good indication that I have too much phlegm. They meant something more like the layer of white blood sells that settle out in a bood sample (eep!) according to one historian.
Which one of the four humors do you have too much of?
Me, I'm probably phlegmatic -- sometimes chill to the point of indifference, usually sleepy, low body temp. I should apparently avoid fish and cucumbers (NOOOOO) and eat spices (YESSS).
Ah yes, making stuff the right side relative to the characters, my old enemy. We meet again.
So, no disagreement with the above poster, they speak wisdom. Here's some additional stuff that helps me.
Don't think of the background as a curtain hanging behind the characters, think of it as a set they walk around in. Also, check and see where various common objects come up to on you -- like, my desk hits me about upper-mid thigh or level with my middle knuckles. A low car is about as high as my waist, a tall pickup truck is just over my head, a typical chainlink fence is chest-heigh, etc.
Yeah, smartypants, I hear you say, what about people taller and shorter than me? I feel ya, bro, my WIP page currently has a 6'3" person and a 5'2"
person. For that, all I've got is "Look at real people doing stuff and/or adjust relative to your own height."
Lord knows I'm no Luddite (I say via the internet) but mine is overwhelmingly pencil and ink. I'm able to be faster and more precise and can draw more places. Digital touchups after scanner murders are great, though! I do digital paintings for fun, but they tend to be slower and not as neat.
Our own Jupiter is a really well-written take on robots. (I love any stories about -- at the risk of sounding cutesy or pretentious -- what it means to be a person, and robot stories tend to be exactly that. Big part of the reason I like TNG...)
About a year before I got regular comments on every page. Then, I was hosting on this out-of-the-way thrown together page, and I don't think anyone knew it existed until I got on ComicFury, DA, and so on.
