Check out Sonnet Central, which has some excellent narrative character sketch sonnet sequences from early 20th century.
For early Spanish ones, check out my dad's book, Six Masters of the Spanish Sonnet, where the Quevedo in particular has many with wonderful parodic sketches.

Would you consider "My mistress's eyes are nothing like the sun" to be a character sketch? If so, there is the long blason tradition in France to consider.
Good luck! I'd love to see a list when you get it all together. I collected what I could on this when researching the sonnet narrative sequence tradition, but didn't go all the way back....
