Well thought use of Colors. Green is indeed friendly for the target audience of life coach, etc. And the font gels well too. Have you had a look at it without the silhouette? Or maybe you could consider one with a blurred image of a woman in peace in the background.
I feel that this design is a bit too green. The colors are green, and photos of nature are used. I think that especially with words like "resources" the first thought isn't about a life coach. Also in the first card the silhouette of the lady seems like she's really small in the grass, not necessarily "tapping into her strength" But of these, I think the third one is the most professional looking.
The middle concept is a good start but still unfinished. All of the concepts here seem ok, but look like they could be taken a step further. Try and add some shadows, strokes, gradients and such to make these designs look more polished.
i like the second version most. But maybe would check on the typo (some capitals, hierarchy) and motive (stronger, more powerful).
Objective: to get woman calling the coach
ruff call - if it where me I would be looking to narrow that down some. Your work is neat and tidy and the concept is ok but without a target demography
