there are some big changes to the archery perktree and a minor changes to the stealth tree.
If you have any mods that alter these two trees, there will be most probably some incompabilities.

first of all the new skills in the archery perks are.

-serrated arrowheads-2 stages,passive,requires 30(60)skill
causes bleedingdamage overtime.the damages stack which proves useful against enemies with lots of
health or fast regenerating opponents like trolls..

-Trickshot-passive,requires skill 80 and the skill -hunters discipline-
the skill was already implemented in the CK,but never made to the game.
A succesful hit will make them drop their bow and draw melee weapon instead.

-bullseye-2 stages,passive required skill is 100(110)
i never liked theoriginal bullseye skill,because first .the chance for hitting it
is just to high,secondly,there is some nuisance when shooting longrange you will notice the aim is getting paralyzed
even before the arrow actually hits it.
this problem is described in the UESPwiki in the archery description.

so i changed the perk to what i think is really worthy to be called a mastershot or maybe more a lucky shot.
There is a 1% chance to kill every target onstrike careless how much health it actually has .
a wolf with a 100 hp will die,aslike as an dragon with 10000 hps.additionally damage is raised by 25%.
The chance is raised to 5% at second stage of Bullseye and additionally crit damage is increased by 25%.

-overdraw-passive 5 instances.
so from historic knowledge the invention of longbows and crossbows caused the end of the
classic knights in full plate armor.Battle of Agincourt as example.

So if an archer is capable of overdrawing his bow i thought it would be only reasonable to
not only increase the damage but alongside increase the armor negotiation.
This means every skill put into -Overdraw- will raise damage 20% and also ignore 20% armorrating of the target
up to 100% with all 5 instances of the perk.
it sounds overpowered but you will see on legendary difficulty that it will just help you to merely survive a battle or
do visible damage at all.

i also altered the quickshot perk from 30% to 50% more drawspeed.
I left the critical perks and eagleye unchanged to make the bow not to powerful on lower levels.
all benefits come with bullseye perk which is for high level characters.

the change to the stealth tree is ,that now you wont be forced to probably waste a point into backstab,
if you really want to play as an archer .
-deadly aim is already obtainable with one skill in stealth.
-The factor for sneak damage is raised from 2x to x5
