Hello everyone,
Firstly I apologise if this is the wrong forum to post this in but I think I got the right one

.
I recently picked up wargaming after a friend showed it to me and bought some stuff on recommendation of shop workers and friends.
Now when I started putting together my models and found out some can be assembled differently.
My friends decided that 750 points was a good army cost to start with so I am here to ask for help as to what my 750 army would look like.
Here is what I have currently:
I will mention if I assembled the model already or not so you know what can be put on what (I hear points cost differ as how you assemble them)
1 x Tyranid Hive tyrant / The Swarmlord (not yet assembled, visually inclined towards Swarmlord)
1 x Tyranid harpy / hive crone (not yet assembled, like both visually so no preference)
10 x Tyranid gargoyles (not yet assembled)
1 x Battleforce containing:
16 x Termagaunt with fleshborer (assembled)
16 x Hormagaunt (assembled)
8 x Genestealer (not yet assembled)
3 x Warrior (not yet assembled)
3 x Ripper swarm (not yet assembled)
I am willing to buy some extra models but nothing to big as I have spend enough before playing a proper game already
I hope this is enough information to get some help with a army list.
Thank you all in advance.
