Just a couple of things. One, I wouldn't put it as improvising "over" major or minor scales. Generally, one may improvise over major or minor chords or a set of chords called "changes". To this note, please feel free to use the search function for looking for these types of tips. Two, F minor is not usually used as a relative to D major. It is generally the reverse (F major/D minor).
That said. There are tons of tips on chord scales, pentatonics, hexatonics, and so on in the Jazz and Improvisation part of this forum (i.e. where this thread is posted). Have at it and enjoy.
PS - you would be wise to find a reputable private teacher to really get this stuff happening.
