I definitely went overboard with Lucretia, I agree. Hafiz is overpowered at the start, but I don't go into the Fortress right away; sometimes I don't go in for weeks. I only send in an army of Cockroaches, and I have nowhere to spend the mana because I don't have any starting spells, so it turns out that Knowledge and Sorcery are completely useless. I would like Talannar and Olhar to be more powerful than they are now. Talannar's machines don't save him; he has 0 attack. I don't like the enchanted ballista because the enchanted arrow doesn't turn off, except maybe for sending a siege unit to attack a city with a catapult, but that won't work 100% against mages, dwarves, and the League. Olhar is too situational for the bonuses he has.
By the way, recently I only played one full and interesting game as Tevaril with a human and 6 companions. I finished the game in the 5th month with 4 squads of 600 nymphs each, 40 Ancient Ents, 22 Emerald Dragons, and 280 Death Dancers in the final battle against Dark Sarah with mini-artifacts and various magical items. I was saved by the Ring of Swiftness, half a set of Dragon armor, and boots +1 to speed. I had upgraded Retribution, Aura of Swiftness, Tactics, Mentor, Skilled Light, Skilled Lore, and Find Path. Despite her insane artifacts and mini-artifacts, in the very first turn, the nymphs alone destroyed a third of her army. That's pretty harsh, considering that they were increasing by 28 per day in the last 2 weeks before the battle.

If you like any of them, let me know;)

I liked portraits 2, 1, and 7, in that order of preference.
