Final answer:
Dorian's sketches likely include recurring elements such as classical faces or hands, sea creatures filling space, and a blend of structured and spontaneous lines, reflecting both classical influences and a mix of freedom and deliberation.
Step-by-step explanation:
Based on the provided references, it appears that in Dorian's sketches, elements such as figures that might carry a similar face or hands, use of sea creatures like sea urchins, coral and triton shells to fill space, and a possible emphasis on pattern and linearity seem to recur. These sketches may also exhibit a contrast between free-spirited scribbles and more deliberate pen strokes, suggesting a blend of spontaneity and structure in the drawings. The descriptions suggest a strong influence of classical themes and techniques, such as the reference to the harmony and proportions sought by the sculptor Polykleitos and the emotion and tension captured in Hellenistic sculptures like those of the Dying Gauls.
