One before Beyond's right hand, one a little down from the jaw which Buniq is holding, one between her elbow and shoulder, really close to her arm, one diagonally from it and one tiny a little to the left. At least that's the ones I see.
Hope it doesn't sound snotty, just that I often have trouble seeing these myself in my own work.
When I want to make the background transparent, I paintbucket the background to a very striking color which is unlike the others (here I'd go for tyrian.) then I use corel paint shop. Easier to not take the wrong part and to get them away then. Or so I think. never tried photoshop for this.
