Graphic Designer for Brand Development Project

My company Karma House Bali is developing a sub-brand for our events department. The deliverable for this project is four main graphics for each event category and one banner graphic for one of those singular categories. The event categories we are working with are; Dance/Yoga, Breathwork, Personal Development/Growth, & Sound Healing/Tantra/General Healing. For these four main focus areas we would like to create a concept where we play with the four elements; earth, air, fire & water. Here is how that would look: Just Breathe (Breathwork) - Air Just Move (Dance) - Fire Just Grow (Personal Development) - Earth Just Feel (Sound Healing) - Water More offerings can be slotted into each category later, but whatever we end up creating event wise will always fall into one of these four categories. The graphics we create will go under our Events tab on our website. What we're envisioning is four images equal in size as a 4 square grid. Each of the images will correspond to one of the four categories and will have type overlay that says: Just Breathe, Just Move, Just Feel & Just Grow. I have attached some image samples for what we are looking for to provide some inspiration. Each of the four images should have a color scheme that matches up with the element. We like the cloud taking form (slightly abstract) design concept and would like to see the contractor use that as a theme but then make each one individual so they stand out from one another. Size should be high res and square. NOTE: the cloud image is quite complex. Using good stock images would be fine if this is too difficult a graphic to produce from scratch. The final banner image is for the Just Breathe campaign. When the user clicks on the Just Breathe thumbnail a new page will open and there will be a full left to right banner (2500 pixel width, full screen image). What we would like to see is a concept similar to attachment starting "87ff" below. The image should show a woman face going through a transformation. Dull and slightly (blurred same as the image provided) on the left side and transformed and bright with color on the right side. See image example "brain." Breathwork is a transformational offering so the image should depict that well without the user having to even think about what it means. It should clear at first glance. There will be a bit of additional copy that will overlay on top of these images. However, we would like to see the image creation first as a stand-alone graphic. If you have any questions please don't hesitate to ask.
