You didn't add "Singapore" to all the animal flowers. Liu Hai and Zhao Gong Ming and their matched flowers are also animal flowers, so should be treated the same way as the others. I never saw or heard of these big turtle, little turtle tiles, but last night I noticed that in one of my sets there are two more animal flowers: a monkey paired with something round, not sure what it is, on a branch. Either a fruit or a nut. Are you sure your set needs to include every conceivable variation on an animal flower?
Very well, deleted and stopped with the "animal flowers" adding.
BTW, you said "since in the list there are no references to it"? On the Malaysian mahjong website it clearly says:
4.......Faces (or extra Flower)
4.......Animals (or extra Flower) **<--- SEE
4.......Fly (or Joker)
Not a problem, will leave them as is now and stop.
I still think you need more red fives. A standard Japanese set would have four (and some would have more).
Actually I'll let it be 9 (3x3) since each page of the PDF will have a 3x3 card grid.

I believe these 8 red fives were placed to fill up the necessary space on the pack.
So this is updated version:
4 x 9 Char,
4 x 9 Coins,
4 x 9 Bam,
4 x 4 Winds,
4 x 3 Dragons
4 x Seasons
4 x Flowers
9 x Japaneses red fives (3 x 5 bam / 3 x 5 char / 3 x 5 Coin)
4 x Vietnamese kings
4 x Vietnamese queens
3 x Vietnamese The General : can be used instead of any suit tile
3 x Vietnamese Dragon Lady : stand for any dragon tile
3 x Vietnamese Lord of Craks : stand for any wan tile
3 x Vietnamese Lord of winds : stand for any wind tile
3 x Vietnamese Lord of Dots: stand for any pin tile
3 x Vietnamese Lord of Bams : stand for any sou tile
3 x Vietnamese Big Flower : stand for any flower
3 x Vietnamese The emperor : stand for any tile
4 x malaysian fly
1 x dragon
1 x pearl
1 x bird
1 x cage
1 x cat
1 x rat
1 x cock / rooster
1 x worm
4 x face (interesting this one, looks like a normal card joker)
