afterlife

I think I've given up on using capital letters in poetry. It may be grammatically incorrect, but lowercase stanzas are much more satisfying.

Is 'afterlife' an appropriate title?

Okay, these are questions for my long-time watchers:
Are my poems better when they aren't depressing?
Am I becoming a better writer as I continue, or were my original poems (cough, the ones with correct grammar and happier topics) better?
