I see an awful lot of artists' statements where the statement makes the artist sound like the best thing since sliced cheese. Unfortunately, more often than not, the images don't live up to the hype. An endless list of local or unknown contest results doesn't really do much good; perhaps unless you won. Second or third place or an Honorable Mention is worthless. Remember, as Vince Lombardi said, "Second place is first loser." Also, if I see another use of the word passion in a bio, I may barf. Typically it involves something like, "I was born with a passion for photography;" or something similar. Calling yourself an amateur or newbie artist can't help, either. Would you go to an amateur or newbie doctor?
Typically, I dislike third person statements, since nobody knows who's saying it. Most of the time, it's a poorly disguised attempt to convey the impression that someone else likes the artist or the work; or that the artist is well-known. I think it's better for the artist to honestly describe themselves, their artistic viewpoint, and their work in the first person. It's more engaging to the reader, like the artist is speaking directly to them.
