Hi @Alexandra Filip, nice studies! When doing anatomy studies I think I would recommend drawing all the muscles at some point, as if it's an Écorché (though this can be done lightly; and the finishing lines might reflect only how it looks on the surface). The point of anatomy studies, is to study anatomy. But, the more skilled you get, the less of the hidden things you'll have to draw; you'll be considering them mentally. Further down the road, you might also have a different focus in your anatomy studies; when you know the muscles thoroughly, you might focus your studies on how to shade the forms. I'll try to look for things to improve on: - The figures feel a little stiff. It seems like you did an underdrawing with marker, then inked on top. Rather than drawing boxes in the underdrawing, start with an underdrawing that's primarly focused on gesture. You might want to look at @Glenn Vilppu's or @David Colman's work for inspiration. Maybe the demos in this video could help: Roadmap. If you want you can work in 3 layers- a gesture layer, a box layer, a muscle layer. Though it might be a better idea to draw the skeleton rather than boxes. In the gesture layer you will already have considered the major forms, and the skeleton will provide enough structure to add muscles on top. Also, rather than thinking of gesture as a separate step, try to always draw with gesture; look for the gesture not only in the pose but also in the construction, the skeleton and the muscles. - I would encourage you to practice drawing figures from imagination. It's a good way to check how well you know the anatomy and to get to know it better. Draw a pose from imagination, see where you're off, study that, draw another one. The middle drawing shows some uncertainty of how the erector spinae originates. It's a bit high and wide. The bottom left drawing shows some uncertainty of how the latissimus originates at the 7th thoracic vertebrae. Also remember to wrap the lat around the form of the ribcage Hope this helps :) Keep up the good work
