We hope to finish the writing by November when Shaarei Tzedek plans to bring in a sofer from SoferonSite to do a program re Sifrei Torah.  The plan is to have a "siyum" to mark the completion of the writing of the Megillah and sew the 4 pieces of klaf together, under the guidance of the visiting sofer.  Not sure if artwork will come before or after.  Artwork will be minimalist so as not to be distracting for a reader.  We are now looking into sources to find a basis for allowing artwork (l'chatchila).
