Hey Carol, thanks for that. The pattern I saw was that the added sharp is a semi-tome down from the new key. Start from C go up to the V and add the natural vii as the sharp. C -> G and add the a semi-tone down from G (F#) as the sharp. Go from G up a V to D and add the semi-tone down from D (C#) as the sharp. Go from D up a V to A and add a G#...
By the way, that's a cool chord you tabbed out
