Seems like one can do much better with transfers here:

1D - 1H - 1N:

2C: Transfer to Diamonds
      P: TP
      2H: Invite
      2S: GF, D+H reversed
      2N: Invite
      3C: GF, D+H, LL
      3D: High short
2D: Transfer to Hearts
      P: TP
      2S+: GF with SS hearts
2H: GF reversed Spades
2S: GF revesed, Clubs
2N: GF LL, Clubs
3C: Long clubs, 4H, TP
3D: Long diamonds, 4H, invite

You saved room, but you left out GI 4H/5 other. I think you need those. Also, pretty much all of my bids are transfers. I transfer to clubs but your 3C is to play. Shouldn't that be invite?

I do like that you left out the impossible 5S/4+H holdings. I just didn't want to remember those. Mine is basically standard symmetric.
