Some of the most treasured QSLs in my possession are hand drawn. I'm not an artist so the best I can do is align text and graphics using a computer. So long as the QSO information is correct, it's fine by me. One of the first QSL cards I received years back the op cut letters out of some magazine and glued them to a picture post card for the QSL to me! Everything else was hand written. I've received cards that have ranged in size from business cards to larger fold out cards. They are all welcome even if they don't always fit nicely into a stack.
