Good job here! :) First of all, you do need to put a little more effort into getting cleaner lines. :D The concept of "T-lines" depends to some extent on line quality, since using thicker and thinner lines where forms overlap is what helps create that sense of volume. :) On the other hand, something that helps me draw T-lines on these types of cylinders is thinking about how the overlapping lines follow the contour and direction of the form, rather than just being straight lines. Notice that in the examples I drew, I indicated the contour at the same level as the T-line to illustrate what I mean. I'm not sure if this is technically the correct way to do it... but at least it helps me indicate these lines more clearly. :) Hope this helps! | Artwod Feedback
