I have to make a digital drawing that has implied lines and includes a classroom chair for tomorrow. It's for my 2d Studio class, the drawing is for the breadth section of my portfolio. For some reason I'm having great difficulty with coming up with an idea. I took lots of photos for references, but that didn't seem to help at all. I'm not used to assignments like this. Normally I just make silly animations, fan art and whatnot.

Can anyone link me to some artwork that demonstrate good use of implied lines? I'd appreciate any tips that can help get my creative juices flowing, lol. Thanks in advance.
