The one on the e extends too far to the left for a start... I think the ogoneks would look better of they were narrower, and used the same angle as the end of the e (extending naturally back from this) - and this will also make it parallell with the bowl of the a?
My 2 cents ;)

Roger is right; for more specific info, look at Twardoch's Polish Diacritics: how to?

How about now?
