I see what you mean - wow...
the voldemort/harry showdown though - is a good concept to have as cover art.

my version (Australia) shows ron, Hermione & Harry in the Gringotts vault with the gold that multiplies upon touch.... how is that really crucial to the plot I ask you??? egh...

I'd rather see a forest covered in snow with a doe patronus.... I think that would have been perfect really
