I prefer the leaner muscle on the bottom two, but they're all excellent! You're anatomy is already so excellent, it's awesome you're working to improve what's already there. Some people get what they think is 'good enough' and just quit trying to improve right there, but you keep going and going
Aw thanks, Toa! I think it's the artist's complex to be forever in a state of "I'm not good enough," rather. XD Though yeah, I have seen some people who like to stay in their comfort zones, and never want to move out of that. Its sad u.u
Straying out of my comfort zones is what urged me to draw heavier characters as well as muzzles instead of normal human faces, and hopefully what will push me to mastering muscles, courtesy of help from your refs of course xD
These are awesome! Lower right pose is fantastic, it has great weight balance, and you are very good with anatomy as it is. You have a real knack with feet, I'm sure it's due to all the practice you get doing them, but they are superb.
I've actually been doing this lately... more importantly I've been trying to find relations in the human boy using the golden mean an so far its been hell, a lot of measuring and whatnot. you wouldn't happen to know any of these relations in proportion would you?
I do indeed! Proportion tricks are an artist's best friend. At first it's a matter of memorizing them all, and making sure you make everything neat and proportionate, but after a while it becomes ingrained, and second nature. Then you can freely draw the figure in ANY pose, knowing those tricks.
