Same comment as before about exaggerating your lines of action to give your characters some better flow in them. It also looks like the ink got a little bit away from you at times on that last picture of the post.(my rant about line weight--sorry I give this rant to everyone at some point...p.s. I don't know how much of this is true, but I still pass the info as if it is. Line weight is something that has grown into something else over the years. Line weight can be used for purposes of clarity that can help separate elements from the foreground, middle ground, and background. Line weight in animation for years was always a deadline. this was because of the difficulty of trying to replicate it from one cell to another. Line weight in comics merely was created by the tools and the manner (happy accidents created by gravity) in which they used them and was less about (technique) making an aesthetic choice as they were just trying to get there job done, as the art form in its early stages was look rather poorly on. over a period of time people became a fan of that aesthetic and began to theorize on why they did their inking in certain ways--now there is a multitude of theory's on how and where and why we add line weight... all I can say is, don't get caught up in it. It is not that important here in this stage, but if you want to add it, just thing about gravity. the line will have more weight the more gravity it has, but really line weight is only important as a device to increase clarity to the viewer.
