JPEG and drawing generally don't go together, and, in spite of a few
gradients in this case, I think it is true here.
Moreover, the actual PDF file has the equivalent of PNG's (FlateDecode)
embedded. If you did produce a JPEG intermediate, that can be about the
worst thing for file size. PDF is capable of storing files in formats
very close to JPEG, GIF and PNG (DCT, LZW and Flate).
Both Distiller (Adobe) and ghostscript (GPLed) can generate PDFs with
DCT encoding, but it looks like you are using another third party PDF
encoder, and maybe it doesn't have good bitmap image support.
(It's not quite as bad as doing circuit diagrams as JPEGs.)

That's unfortunate, as it is one of strengths of PDF that it is a vector
format (it annoys me when people embed simple research graphs in bitmape
form, losing detail in the legend, when the format could handle a fully
scalable image).

Rendering direct from PICT to PNG is likely to produce the smallest
file. It might be worth experimenting with palletised versus full
colour. There are tradeoffs in compression either way.
