Artemis Fowl Age Chart

I was bored so i made an age chart for Artemis. I know that the two 15's look like they're different hieghts, but they're not. They're just standing different, AC 15 has his head down and is kinda slouching, and LG 15 is standing on his toes.
0 and 5: These were never talked about so i drew what i thought they'd look like.
9: He's 9 - 10-ish. I figured by now he'd dress nicer but not wear business suits everyday.
12: We all know about 12-year-old Artemis. He's posh, proper, usually plotting and schemeing, and always wears his suit.
15(Atlantis Complex): Oh, doesn't he look so distraught? Artemis was admitted to the J. Argon Clinic on his 15th birthday for treatment of the Atlantis Complex, what an aweful birthday. I didn't know what clothes to put him in, so i drew him in the "Randomosity" shirt and jeans his mum got him.
15(Last Guardian): I wasn't too sure what age to put for this one. Artemis died and was ressurected in the body of a clone, so mentally he's 15, but he's only really existed for 6 months... Anyway, you have the clone standing there in its hospital gown that's not quite long enough.
