It's not the best drawing, although the only way I can improve is by practicing, if you have any advice I'd like to hear it.

I wanted to apply the knowledge learned in class to something outside of the shapes in the video; this is the cover of the Transformers, I traced the outline of Optimus Prime, then I highlighted the lines to improve the line quality and tried to apply crosshatching for the shadows, I don't know if it is noticeable due to the quality of the camera but I think it gave a good result.
