I didn't really learn anywhere. Art at school was always below my skill level, so I just taught myself in my free time, its easy to learn and become good at something you really enjoy
Though I must credit my Digtal Media teacher, who told me the crucial basics to 3D art, which from there, I went about myself and practiced things I wouldn't have been able to do without knowing the basics of it, as 3D art is VERY different to 2D digital art like Photoshop ( in which I'm ENTIRELY self-taught
, and yes, I started out totally Noob-ish too, my earliest deviations aren't the worst things I've created lol )
