Not got the book to hand but i think your heros are too expensive, in 1k you can only spend 250 total on heros and at first glance yours are worth more then that, but i may be wrong.
For Scar-vet, drop the carnosaur pendent and take shield and light armour, this gives him a 3+ save and cheaper
For priest, drop rod of storm, take Plaque of Tepok, then he'll know 3 spells.
I'd drop the brave and stalker from the 2 skink units, there just not worth the points IMO.
This would then leave you with about 50 points ish for a few extra skinks perhaps.
Its an idea but i'm pretty sure you can't field those heros as is.
Hope this helps
