Great value choices! Try doing more studies but without using linework to separate the subject matter (like outlining the people, chairs, boats, etc.) so instead the focus can be on how the values themselves break up the picture. Sometimes subjects will be combined with others (like how the standing man's face blends with the same value as the background) or be broken up into different values (like how the same man's face has some white light hitting the side). Thinking more about the abstract shapes of the picture is a way to examine the compositional and value choices made by the artist more directly.

Hey @Eryk Świątek, nice job with this assignment! I really like the flow in the top middle one. I noticed something happening in the ones where the seal is lifting its head up and twisting, it seems like the seal is segmented into two parts that don't connect well. I included this example from the video to show what I mean. Try drawing through where the point of contact is -- this will give you an idea of the form even though a flipper or something else may be covering it.

Looks great! Your lines get a bit scratchy in some areas in the penguin drawing, but overall nicely done 👍
