I just quickly checked out the first page. Its a little bland, and I would re-work it from scratch but for short term practical improvements you need to:
- add more left/right the internal margin to the blue bordered highlight box. Maybe make that blue match the banner as well.
- Rework the composition of the text on the banner, looks a little strange and lacks impact, to me anyway.
- and I would remove the dark outline and glow on the apple graphic, give it a clean edge on top of the trees photo, which could then be used more promoniently i.e not so transparent esp. if you fix the text design.
just my two cents since you asked, I'm sure there are other opinions or ways to critique it.
