Own branding patterns

After Experimenting with different colours and patterns for my branding I have decided that these will be the final designs, there will be 4 different designs for the business cards and then the patterns will be applied to all other branding, such as envelopes, letter headings and  other forms. 

I think the colours in the patterns could also be linked to the seaside, or the sun and sea, this is relevant to me as it is one of my favourite places to be, the pattern looks like waves also and the yellow could be sun.
