Helga Thornfall Alliance army "The Opera"

Can't help on the painting front I'm afraid. Triple Valkyries and two trenches help to make any list kind of resilient on the approach, and the War Hogs will help make up for damage. I'm not sure about the Commandos though, I don't think they can be relied upon to every do the kind of work they seem like they should be able to do on her Feat turn, and I generally think a second unit of Brigands with a Warlord (replacing Maximus) would be better even if it does give up some board presence. Alternatively, a Meat Thresher (replacing the Chef) is just hilarious fun with her. It's also a decent beneficiary of Defender's Ward, or it can drive up the defence of a Defender's Warded unit of Brigands even further.

On the solo front, I think there are better uses for the free solos than the pig solos. Efaarit are pretty good with her, allowing you to enable her Field Marshal pretty easily and also acting like mini-Meat Threshers by slamming with their impact attacks on Feat turn. Along with the Meat Thresher, they would also provide you with some fast moving, reasonably powerful shooting that can help your slow pig infantry jockey for position in the early game.

I do think Helga is a fair bit stronger in WWFF, but in a casual play setting you should be fine.
