Do not let worry over what might be expected of you stop you from showing what you can do, just do your thing.
You are afraid that if you show to others what you can do, more will be expected of you and these expectations will prove too much. But if you let this stop you from pushing yourself forward and trying, you will be stuck with never knowing what might have been. Use your creativity to lift you up and do not worry about expectations, just do your thing.
