Using skills in performance

In our performance I decided to use my skills. Personally I'm a drummer. In a metal band. And I thought it would be a really good idea to use the drums in the part at the end of the piece when tom kills Ellie. It will add so much more effect and I've actually written a piece. It's constructed so that every time a bunch is thrown. I hit a cymbal. It looks really really clever. And we got loads of good feed back from the other group and from the audience. When it comes to the end of the attack scene. Before Ellie is killed, tom is throwing constant punches to Ellie. Whilst he is doing this. I play a lot of fast double bass parts and also tom subconsciously heard Kyle shouting things to tom.. Which shows that Tom is clearly a sick man and has gone insane. I do feel that maybe we could have incorporated more skills into the performance. I know I involved drumming but maybe the other members of the piece could have done something similar?
