Welcome to fantasy! Dark elves are a great place to start however unlike
40k the army break up is different, looking at your list it looks top heavy and possibly illegal. You start with a point target ie; 1000,1200,1600,2000,2400 are good targets, then apply the structure so a minimum 25% core, maximum 25% for hero's, the same for lords and finally hero's, then a maximum of 50% for your special choices.
I THINK you have two expensive lords which can't be 25% however that could just be me
If you put the total cost next to the units you'll be able to see the break down easier
