Did this practice with my usual pencil grip and such since these werent supposed to be quick sketch figure drawings. At least I don't think they were supposed to be, apparently theres a second part to this assignment but the reference images for both the first and second part are locked behind the stupid fucking premium. Thankfully I just looked through the completed ones others submitted until I saw someone had all of them for the first part and just cropped out the ref pics lol.

For the first one I tried to think about the like edges (digits??) of the muscle as it connects to the tendon over the abs but I decided not to for the rest cause I though it'd be better to at least for now just focus on how the obliques squash and stretch. Perhaps in the second pass or if there's another assignment part besides the one thats locked behind fucking premium. I also partway through tried to be less chicken scratchy but it seems if I tried to make a nice solid line I end up pressing down too hard (and then end up chicken scratching anyways cause the lines are wrong). Other difficulties are yknow perspective and shit, having difficulty getting the bucket of the pelvis looking right etc. Lot to improve at.
