I really like the colours you've used. Is it possible to make them "pop" a little bit more? I'm not very good with words to describe colour, but I wonder if the sage green and grey can be a little sharper so they stand out more?
I'm not sure about the person's head on top of the "e". I think I'd prefer a plain "e" or a stylised pilates image. I will try to upload one I've seen and quite like and have used myself on brochures previously.
