Right, I've changed the age to fourteen and put a little more emphasis on his skills and knowledge regarding combat, tactics and the Echani cultural knack for reading the body language of others to reflect the fact that he's spent even longer raised in the Echani society. As far as the changes I made to his lightsaber skills it's basically just to reflect that he's using Echani styles of swordsmanship with his lightsaber and a little bit of basic Shii-Cho to try and cobble something together, but he's too inexperienced to really use actual lightsaber forms very effectively.

Overall he's a little smarter, more skilled and more mature than the young child version would have been but there's still a lot of immaturity, inexperience and room to develop in a wide variety of directions, which is what my intent was anyways. Let me know what you lot think and I'll make edits/expand as necessary.
