Developing the Logo

I did a fast sketch of a logo the other day and tried to make it on illustrator today. It's the ghost and skull in a shape of a heart. And I've been thinking of names for the brand and like the word "sloks", cause it sounds like a cool made up word except for it's actually parts of my name strung together. The logo still looks a lil too cute, and i definitely have to work on the font choice. I want it to look more cool and edgy, instead of cute and quirky.
