Among other artists.
In case you haven't heard, Harley Quinn's upcoming solo-series (first issue in November) will kick it off with a zero issue in which Harley herself will "audition" artists and judge their depictions of her. If I am reading correctly, each page of the book will have a different artist that Harley will critique and in the end she will select who will be her monthly artist.
Not all of the artists have been revealed yet but a fair number are listed in the above article. The name that stood out to me was Bruce Timm. He co-created Harley, was involved in most animated DC material, and was artist for Harley's most famous comic: Mad Love. This just makes me more excited for the upcoming series.
