Hi @Dylan Doster, nice work. These are looking pretty good. - I would study the attachments more. They feel a bit incosistent, as if the muscles were hanging loosely. Decide on exact points and try to hit those same points in every angle. In the 2nd drawing from the left in the bottom row for example, the abs originate too much to the left on the front plane of the ribcage. Before drawing the muscles, find the centerline of the rib cage and make sure the muscles attach correctly in relationship to it. One thing that helped me with the external oblique's origin was to imagine a line running through all the origin points and study were it is. - Try to make a more clean presentation of the work. If you're doing it digitally, save the work as an image and post that. It's good practice for presenting your work as a proffesional, plus makes it easier to critique. Hope this helps :) Keep up the good work!
