Your inspiration from Dave Chappelle is very obvious. It's okay to be inspired by a comedian, but you need to find your own voice, figuratively speaking. People are going to notice the influence and some will find it insincere' given how close it is. For example, Chris Rock is heavily influenced by Carlin, you can notice it in the stage presence, the subject matter etc, but everyone knows a Chris Rock joke as a Chris Rock joke because he puts his own experience and personality into the works.
Also as previously mentioned, you're pretty quiet, which gives a sense of insecurity, which you really need for something like comedy. Crowds are not forgiving in comedy and unlike something like music or theatre, you don't have an instrument or an act as a guard, or friends. It's just you alone. Confidence is key.
