The archetypes is presented in five pages: cover, two pages of description and two of OGL. It could use more context for the archetype such as suggestions for where they might fir into a game world and what sort of culture would inspire them. Also, and this is very common for such materials, is a lack of support material such as a new spell, magic item, place or even a legend to inspire adventure would make them some much more interesting and easier to fit into a campaign.

Cleric of the Beast Domain give some Druid/Ranger adjacent abilities, movement through terrain, an extra thematic skill. Frightening Ally needs a better name and better description, perhaps Roar of the Beast? Beastly Attack, again a better name would be helpful, should be restricted to adding to one attack per turn and adding force damage (which useful) does not seem very beastly to me. I would increase the dice size and make it the same sort of physical damage the weapon already inflicts. Nature Spellcasting as their capstone ability seems a little inflexible, maybe choose four (or even more) Druid spells none of which may be from the same level for it to effect?

Good idea, but needs a little focus and refinement.
