I'm really surprised no one has mentioned xxmichaeljames.. He's pretty "new" I think, but I LOVE his style and technique. His tutorials are clear, easy to follow, and most importantly (to me) he speaks loud and clear into his mic.
I wish I could get away with doing makeup like his everyday.. sadly, I don't think it would be appreciated at work haha..
I also love xsparkage (her videos got me into makeup), petrilude, vintageortacky, trashyfag, and to have some balance I subbed to a girl called makeupologie. She's fairly new and upcoming, but fantastic for "neutral" or simple classic looks.
