Does Buddhism kill creativity?
Many working artists are also Buddhists. A number of high profile creative people such as Leonard Cohen, Herbie Hancock and Steve Jobs are Buddhists. See Wikipedia's long list of celebrity Buddhists, many of whom work in creative industries.

Most people report that creativity increased after taking up meditation. At least one scientific study reported that meditation enhances creativity. The Huffington Post has reported much the same news. 

Buddhist practice requires not just moment to moment awareness, but also considerable continuity of purpose. If one emphasises only the former then one is unlikely to make much progress. It's a bit like walking downstairs and forgetting why you went down there. 

So there seems to be no reason to think that being a practising Buddhist would "kill creativity". And no reason to think you cannot balance being a practising Buddhist and a creative artist. I personally know at least a dozen people who do just this.
