Development on Designing

I have recently been putting my photographs into Photoshop so I can start designing. Picking out the shapes so I can see them in different colours from my colour pallet is really helping me to see how my colours look and work within different shapes. 

Doing this before getting straight into designing I can see how big or small I want the shapes and also the colour. This process is even helping me discard of any shapes within the photographs that I don't think suit the look I am going for, which is Natural and subtle shapes.
