I've kinda been a peruser of CA for a while now, but I'd like to start contributing... so here you go
if you don't mind the suggestion, start drawing the outer edges of your figures with harder, crisper lines. it may not be your style, but i think it will contribute to your feel for anatomy.
Hey, Ian! These are a little late but may be a huge help for future reference!
Hope those help, man. Try and do what the photos have done, in general, for all pieces. Capture the values and tone as rich as they truly are, bright brights, dark darks, and rich midtones. If you want to manipulate those to fit the mood of your piece, then you'll know what to do a lot easier once you understand where your colors are coming from, and how to bend them to how you like!
enviros looking good, same old same old advice with learning anatomy, we all repeat ourselves to people time and time again, but it's really true.
Perhaps try drawing your figures before painting them, even oil painters start with a drawing and only people highly familiar with anatomy and proportion 'carve' out the body. You can't spend too much time learning the human body - and in fact, everything else will become easier to draw because the human body is so complex!
“It is enough that we set out to mold the motley stuff of life into some form of our own choosing; when we do, the performance is itself the wage.”
"The most beautiful thing we can experience is the mysterious. It is the source of all true art and science. He to whom the emotion is a stranger, who can no longer pause and stand wrapped in awe, is as good as dead; his eyes are closed." ~Albert Einstein
