I partly agree with Elleray on this one, even though you indeed have some nice things going on. Change the colours on the middle pic, as mentioned above. One more thing I'd reckon you should do is perhaps to not have such a "uptight" colour-schedule for (at least the first chick). You can of course stick to one tone of some colour, but do take advantage of nuances! Well well... You could try to put in even hotter chicks, but that's just a thought from somewhere not-so-deep within ^^.

Keep it up, dude.
