I'd say that the best moc you've ever built is... your self. Seriously, it isn't as big as Ancient, but the concept itself combined with the epicness of it got me. As said, Ancient is really good also, love the cannon arm. And don't forget the Sand Monster! I wanted it to win BBC#54!!! Anyway, VB is just epic with more epic on it. It's wild, it's savage, kind of mutant -ish. It's that that makes your mocs kind of unique: your style makes them look like mutants, distorted and monstrous (in a completely and absolutely positive view) versions of common sets - like VB is for a Bohrok. And it is really creative when it comes to parts using.
Dislike? Several lack of a Kardas moc , no seriously, I think Barraki eyes could do better instead of Viking red spikes. That's all, really!
Ps. I'm sorry but I prefer the old V2 Vampire Bohrok over your new update, maybe it's just me...
