I Need Your Help

So what do you think? I am thinking this could be the logo for my foundation. I could put this on jewelry (with practice makes perfect it will look better next time!) and those who don't want a BTS piece or Brain Tumor Survivor piece can have this to signify support for my our cause! I Trade Mark it and also design the graphic to use on a website to sell it, as well as other pieces, and give info about brain tumors, and support and such. I need peoples opinions. I know many people read my posts, I actually need some feedback on this one. I know it looks a little rough at the bottom, like I said, it is my first one. Please give me your input, what you like about it, or don't like about it, I won't be offended I promise!
