I redrew one of my line-art pictures.
In the first the pose is okay but a bit stiff, which is all the more visible when you draw a simple stick-figure over your art. Smart people would do that step in the beginning stages of their painting, but hey... sometimes I get carried away and I need to make adjustments in the later stages of an image.
I put more emphasis on having a contra-pose, which means that the shoulder-line dips in another direction, than the hip-line. Also his stance is broader and his face is way more active. Looking at reference and acting the pose out helped me here a lot.
So try it out and see if it helps you.
This is my blog.
I will share information about workflow, my insights into image-making or just general thoughts and rants about being an artist.
