Sonnet 4 seemed rather dark at first read, especially since the last line read "Thy unused beauty must be tombed with thee,which used, lives th'executor to be." Rather makes beauty out to be a bad thing if you dont flaunt it. I myself have never really given much for looks, though i do like them. I am, however, not shallow enough to obsess over them.

Sonnet 11 was also rather grim with all that talk of death, although i rather liked the bit that read "She carved thee for her seal,..." i rather think she probably did a wonderful job raising/training her man if he was to become the seal of her tomb.
