Ok here's my opinion!!
Blend 1:
Pictures blended together is done pretty good. I'm not a fan of the border. It's an option in PSP, I know, but if you wanna have a border you can easily create one with brushes, so you have like your own individual one! But that of course is your own choice. Also, the colour to me is a bit too 'burned'.
Blend 2:
It looks like the picture on the right is not in the right size, or maybe Beyonce just looks like that

Overal it's a nice blend!
Blend 3:
Great blend, just again that border that doesn't make it for me. I think it would have looked better without a border. THe colour is pretty and the blending is done well

Oh one thing, the text isn't that good to read (well the Jessica part), but I do like the font!
