Masterpiece
nice. it looks like sango kaku like others said. i just got a regular green palmatum (i also have one as bonsai because that one was from someone who grew from seed or cutting and it was 1.5" thick before i hardcut it)...the new one i couldnt pass up at home depot for $29 because it was almost as thick as yours, roots looks a bit wacky or it is a graft im sure so i might just develop it is a nice patio/garden container tree. they have value to me at that size as well for maples for my garden.
good luck
