You’ve seen my artistic skills. DNA porn 4 lyfe! I wonder if they’ll consider that too adult to be a cover image though….
Oh I already figured out your cover for you.
Harry and Draco, arms crossed, standing back to back on a white background. Draco, on the left, is in a lab coat and has the periodic table of elements and brightly coloured chemical formals floating in front of him. Harry on the right is in a business suit with money signs and math floating around him.
And when you shrink it down to tiny cover size you’ll know which one harry is because he’ll be the 3 black pixels.
