Hello there. I'm João and would like to introduce you to my take on this project.
I did some research using the key words for the brand image the client was after, like feminine, upmarket etc to see what's out there in this niche. Then, I created a design that visually translates the key words, which thus gives the brand the feeling you wanted.
To give the whole thing more personality, I used a mediterranean color scheme (blue, white, and earth tones) tweaked a bit to mirror a more upmarket, exclusive feel.
The design is both feminine and modern, bot not too feminine so that it wouldn't appeal to men in general. The abstract symbol in middle is there to provide a more imaginative, illusive and calm sensation, which I think resemble the villas in the mediterranean coast. The symbol also visually resemble the sun, the earth, which are attached to nature, reinforcing the idea of the marine theme.
