LA should be at least +4
+1 or even +2 for badly unbalanced ability scores (far fewer penalties than hill giant and ogre, for comparison)
+1 for reach greater than 5 ft.
+2 for natural armor armor greater than +5
For CR, I'd go 4. Although it has one less HD than the ogre (CR 3), its ability scores are better, its hit points higher, and its AC is better.
We need to add languages to the main description. The ones I listed in the "as characters" section are the same as those of the hill giant.
