Raoul Dufy was a decorative painter. The pattern of artistic talents in his chart is clear:
Pisces Midheaven (for an not so materialistic goal in life)and...
Neptune is elevated
Moon in Pisces (ruled by Neptune) for sensitivity
Moon sextile Neptune
Moon half semi square Midheaven
Venus semi square Neptune for artistic talents
Venus square Midheaven
Pluto oriental (first rising outer planet), ruling the 5th house of creations
Pluto ruler 5 conjunct AC/MC
He made optimistic and joyfull work and that might be the reason for being underestimated. Venus square Saturn is a good aspect for a stand up comedian or for cabaret. For a paintor it is a less fortunate aspect as it says that his style has it's limitations and perhaps the amount of appreciation, too (in the eyes of the artist).
