Ingres drawings are a sublime view to learn from. I have seen sketches on his trip to Rome, quite small sized, yet full of details in a simple, precise line. Wonderful!
View of Villa Medici, 1806, 12x20cm. (Ingres traveled to Rome and Italy when he won the prestigious Rome Price in 1797, he was 17!) His tudio in Rome was on the grounds of the Villa Medici sketched here.
To me, Rome is the most beautiful city in the world. But I would have liked to have seen it during this period: much more countryside and no cars!

Picasso was also fascinated in a period of his time by Ingres' drawings and also took ("copied" he would say) from him but with his own style: nearly outperfoming Ingres with an even more simple line.
"Drawing is not just reproducing contours, it is not just the line; drawing is also the expression, the inner form, the composition, the modelling. See what is left after that. Drawing is seven eighths of what makes up painting."
Note: Ingres did not like Delacroix's new style of painting
His portraits drawings are also stunning. It's clear that the intention of these drawings was to use them for a painting: the faces are nearly "photographic" (when Photography had not been invented yet) while the clothes and folds were just hinted, albeit very clearly.
