The above photo is my favourite of the three that look similar, this is because you can see that all the boys are wearing different tops, showing off their individuality, however they're all wearing jeans which links them together as a group. Another aspect of his photo that I like is that all four boys are looking in different directions, and having Jack, the lead singer and lead male within the music video looking directly at the camera shows how he is possibly more important than the rest of the boys.
Out of these two pictures the one above is the one I prefer more, even though they are extremely similar. I like how the boys are all standing together and it seems as though they are all looking in a similar direction. Jack again seems like the odd guy out as he is the only one of the band that isn't resting on the pool table which would show independence and possibly masculinity or responsibility, representing his as maybe "the leader of the pack". I think this would be a good photo for the back of the digipak and possibly the first photo at the front, or even have them reversed, so their backs is what they buyer will see first, enticing them in. We could also change the colour to make the guys look more mysterious.
