Start checking the placement of all components and the direction of the component when important (diodes etc.).
Otherwise: post some VERY sharp and CLEAR pictures on a photo hosting website and put the link here.

Solderings look ok but can’t see the components very well: this is not high resolution and very sharp! Too much noise, try making much better pictures with a REAL photo camera, not a crappy mobile. 2 pictures suffice in this case: a perfect one of the upper side and a perfect one of the soldering side (high resolution and SHARP WITHOUT noise).
