PCB models

Here are the first versions of Electric imp LDD board I have been designing. First version uses two different power sources (one for Imp and second for Led string). Second version uses only one DC power input. If somebody out there is kind enough to point my errors on design since these are my first ever custom pcb’s. Size is about 10cm x 7cm and they are made with eagle. First design is based on my current setup and second one is similar but with internal voltage regulation.
