Tree Gargoyles?

OK I'm looking through some stuff and I think I want to make these beasties kind of a cross between treants and topiary guardians. They should be constructs made of raw branches and tree parts that resemble wild animals. But I also want them to have attacks similar to the blight monsters from 5e. I'm going to continue working on these guys and I'll let you all know what I come up with. If anyone has any thoughts, please let me know!

OK Here is what I've come up with. If anything looks out of place, please let me know. I expect to do some play testing with these guys. I'll let you know how it turns out!

This being appears to be a 9 foot tall statue made entirely of raw tree branches. It roughly forms the shape of a wild beast. As you approach, its eyes glow brightly and it takes a step toward you.

Druid Guardians can be made in the shape of any animal. Their attacks vary based on what animal the statue is made to resemble. They are formed out of the forest itself by druid who do not wish to be encountered.

Combat

Druid Guardians stand as statues at the entrance to the druid’s hideaway, only moving if approached by uninvited strangers. They will cease their attack only if they are called off by the druid that created them, they destroy their target, or they are destroyed.

Freeze (Ex): A druid guardian can hold itself so still that it appears to be a normal statue. An observer must succeed on a DC 30 Spot check to notice that a druid guardian is actually an animated construct.
Splinter (Ex): Instead of a melee attack, a druid guardian can launch a volley of splinters from its body at its foes. Shards of wood fly from the druid guardian in a 5 foot cone with a range of 30/60feet. Targets get DC16 Reflex save to take half damage.
Regeneration (Sp): Although technically a construct, if a druid guardian is within 60 feet of its creator, the natural forces around it can repair damage and replace missing pieces. Damage dealt by fire does not regenerate.
Forest stride (Ex): Despite their great size, a druid guardian can move through the forest completely unhindered. Dense vegetation and ground cover are not considered rough terrain.
