done for practice
New version with a heavier font and different colors. I'm very unsure about the colors. Thank for all the help.
Stick with the sans serif in the first version but make it thicker....color are fine and intense keep them. This petit-serif is not ok in my vision it gives more complexity than neccesary to the top of the logo, make it solid enough (wich is now) and simple. Also if you are unsure about colors you can add some darker violet, more wieght there.
