the level 16 creep formed by 3 succubi and 2 felguards are only formed with melee units with no mana and no skills
so:

1-mana burn can´t be used
2- 5 melee units, seems to be redundant,

It is a good mix for enviroment/theme (red units) but I think a caster / ranged unit is missing

the burning archers may fit for the theme and they have burning arrows, a mana burn target.

I think the design is great, the figth starts in the north and then it goes to the south by expanding.

see ya
