Sebastian -great first concepts. The emblem/adstract mark (the medical plus) appears to make the logo too medical or clinical. But I agree it needs something in that space. Healthy success will share health tips from natural sources and to show a lifestyle that avoids the many toxins in ones environment. A strong tie between health and success starts to appear in what you have. The green/bue/grey color is more favorable over the red/bue. Below is a very good health blog with examples of the type of information and products that health success would associate the basis for success.
Feel free to experiement with concepts that are not using bold or blockly text and looks to use cures and flowing style. Great start and I'm so excited to see visions manifest.
Nice concept - the colors are a little faint. Really would like to see a little experimentation with colors to show interaction between health and success. I just have this in my mind to tie this together. Earth, Nature, Health, Success, Business, and richness represeted. I hope this helps.
