Uhm, i'd swap acceleration for martial tempo/bullseye on galvanic shards for some more damage there, will help for clearing mobs.
Ambrosia on HoT definetely not for me, could use longshot or precision there if you got free spirit, you only have HoT so you should have 70 free spirit.
Amulet is kinda bricked with spell damage and armour, +1 projectile is good but other than this one and attributes is bricked.
Left ring is useless, you want flat physical and flat lightning/fire cold first then resistance/attributes/mana or life depending on build need. Accuracy is good becaause of falcon dive and crit chance on amazon but something above 250.
Right ring better but you have %increased fire damage without a fire source.
Crossbow is pretty decent but you want +projectile there (up to +7) and i dont see runes there, maybe add greater storm or greater iron.
Pretty sure someone else can give you better tips, start with rings and swap those 2 support i mentioned.
