Indeed.

Many years ago, I took a poetry class and on the first day the instructor said (roughly): When E.E. Cummings did not capitalize the word 'I', it was creative and original. You are not E. E. Cummings. If you do not capitalize 'I', you are boring and pretentious. Capitalize your 'I's."

Breaking the rules of grammar is good when it adds value to the writing. I don't see how refusing to capitalize added any value here.
