Is it to late to try for this?
Not at all! Just PQ Flip and make sure you have everything you need.
Oh, and everyone's gotta have an avatar. Just like the new ones you see on the page, they gotta be drawn, and have something to do with you or your comic. If your DD avatar works, use it. it's 75x75.
AND a header! don't care how tall or short, but make it 800 pixels wide. and cool. make it cool.
