If I may suggest...
d8 Hit Dice
2 + Int Skills
Good Attack
Rapid Shot is listed as a bonus feat at first level, but otherwise functions like the monks flurry of blows.
Bonus feats at 2nd, 5th, 8th, 11th, 14th, 17th and 20th (like the Psychic Warrior).
At 10th, 15th and 20th can select a compatible archery related feat and gets the bonus it provides improved in some way. For instance, Point Blank Shot might be improved to +2 attack/damage within 30 ft and +1 attack/damage within 60 ft., Far Shot might make the range increment double for projectile weapons and tripled for thrown, or Precise Shot would just grant Improved Precise Shot.
Lastly, the requirements for bonus feats would be reduced by 4 Dex and 2 Attack (except for some feats which actually depend on attack bonus, like Multishot).
Actually, and lastly I might add an ability that allows them to treat any composite bow as having a strength bonus higher than it actually does, based on level.
