I would like to suggest you to take a look at the third animation on the fast attacks (left click), I presume that chain should be for fast shots right? the third attack takes too long to fire, and there is no difference in damage, please make it a bit faster because there is no benefit using it, just 1 and 2.
And the perk on 20 points in Accuracy, change it to 20% less stamina while firing arrows, the Ricochet Shot is nice, but it doesnt help in anything, archers are more fond of being able to fire more arrows before getting tired instead of ricochet shots.
