just a starting comment; i am assuming that "SP" stand for salamanders, but correct me if i am wrong. also include total points for the units or characters.
anyway, back to your list. it has great potential, but you are putting massive amounts of points onto two characters, 655 combined by my count; it is a risky move. though it is all up to you, an alliterative would be to put a scar-veteran into the cold one cavalry unit.
next i would recommend that you put your spearmen into a 6x3 formation so you will maximize coverage. also, you do not really need a champion unless you have a character to protect from challenges, for example you TG champion protects you slaan.
with the points you have saved, depending on how many which i do not know, you can do one of the following:
- give more magic items to your scar veteran or other minor character (again, you can keep the engine if you want)
- give a magic item to your TG champion
- get a unit of skink skirmishers
of the three, i would recommend the last for two reasons. one, i happen to be i huge fan of skinks and their use, and field a skink themed army. two, they are great harassers, and although you already have terradons for this, the skirmishers will supplement them; also skirmishers as a whole ar very useful when dealing with terrain (i.e. stubborn when in forests).
finally, i would advise you to split up your up you salamanders (assuming that is what they are) into two separate units, the work better solo, and depending on how the points pan out give them extra handlers.
i hope i was of help, and also welcome to lustria-online! thanks for posting, and happy wargaming.
