Hi @Lucijan Prpić, really nice studies! You're showing a good sense of form and knowledge of anatomy. - This might be a style thing, so take it with a grain of salt, but I think the sense of structure in the abs could be even stronger. They already read as having form, but they feel a little soft at times. It might help to think more sculpturaly, as if the abs are a block of rock attaching to the ribcage and pelvis, somehow magically able to bend and conform to the torso's movement. Then you can think of each row of abs (or even each rectangle) as a brick. This analogy encourages blocky massconceptions with clear plane shifts. Hope this helps :) Keep up the good work!
