They're all well done! Congrats =) The first snow shot shows that it's a bit over exposed, so next time try to compensate a little (1.0 or lower). I guess it's a matter of the extra light the snow gives...but the rest are just fine. So I certainly wouldn't waste a roll on metering shots, but just try to get a hang of when to correct the metering. Btw, have you ever read Kodak's Guide to better pictures ? It's an awesome online site form Kodak, really interesting and huuuuge with great examples =) Anyway, maybe Alpha or Slynky or anyone else can go into this: I think the next step to improvement is choosing film :)
