When you say change it, what are you referring to? I only ask because on your website there is no mention of studio and you refer to yourself as a freelance designer. Again, the OP asked for advice, perhaps next time I should just nod my head and say that everything looks great. Then if anyone says otherwise then just tell them that not everything is black and white?
I could be wrong but I associate a studio with a team of designers, when used in the context of graphic design because the term for a lone designer is freelancer - and that's why we have separate terms, to differentiate between the two. I wouldn't buy a car and then start promoting myself as a minibus service, or hire two other minibuses and describe my company as a multinational.
Ultimately it isn't a massive issue, and certainly doesn't warrant this level of scrutiny. I'm simply giving my reasons as to why I gave advice on areas I believe could be improved as, you know, that's the point of this thread, to give advice on the work provided.
