Drawn mostly from imagination, sometimes used ref to check anatomy. Not best, but at least I practiced. Tried to add little shadows as friend suggested. Bottom left my fav. Do you have any tips to draw poses more easily or in action?
Hmm, the one at the top left; her boob just doesn't look like it's in the right position (I'm a girl so I should know). I think it should be closer to the arm = move a bit more to the right. Boobs don't just sit still in one place. Depending on in which position the arms are, the position where the boobs are might change since they might be "pulled" by the arm.
As for action poses, maybe you could watch some action movies? Like Die hard, X-men, Sucker Punch, James Bond. Also, dance movies are great for finding good poses to draw, since they tend to use less stunt men, and all the poses they strike are (in) real (life) = automatically anatomically correct. I can recommend the Step up series: Step up, Step up 2, Step up 3D and Step up 4. They got some awesome moves going on! (Plus, the music is good).
It shouldn't matter all that much which gender the main character has, girls and boys can take the same poses and do things the same way. The only time it matters which gender they have is if you're looking at how to place/draw the chest or crotch. That's the only real difference as far as I know. So when you draw poses,
Be careful not to fall into those "traps" of t&a poses or unpractical bikini armour (and all the other types which protects everything EXCEPT HEART, LUNGS AND GUT) just because it might look "cool", "hot" or just because so many other artists do it. Many of us girls feel uncomfortable and/or offended by those things. It's sad that those kind of things still can be found in a lot of video games and comic book.
Don't do it like they do, be original~!^^ One day, artists may very well look up to YOU and YOUR WORKS( if they don't do it already, which they should).
