I don't have much time right now but I did notice a few things real quick
a Heamonculus for 50 is cheaper than a naked archon for 60.
The Warriors are fine, but you are lacking in ranged AT< might want to make 1-2 have Lances instead
whyyyyyyyyy would you take Dissys on the Ravager, make those Lances! also a nightsheild is better for the ravager as you will get cover easy, better to subtract 6 from their ranges and avoid damage than make saves.
Jetbikes are fine but would be better with cannons
You don't need the Exarch on the Crimson Hunter, turn those 20 into cannons for the bikes
Avengers are fine, but if you are taking 10 you plan on them getting out, might want to make it x9 and put a cannon on the Serpent, and find 15 points somewhere to give it Holo-Feilds
Farseer is fine
The Eldar, more than any other army, should not only look at the output of each unit individually, but the synergy of multiple units together and their role in the force as a whole. - Fable
