sorry about the name error, really unlike me. I have withdrawn my other entries and here is a resubmission. I have swayed slightly from your suggested concept as the W in power is not centred and therefore makes it difficult to make a center piece out of. You can leave me individual feedback by clicking on my design and this will notify me by email so I can respond faster.
Here's that version you were after. expanded the purple ring and bolded the font (this is tricky because larger fonts sometimes don't carry the whole way around so I think I found a good compromise). Also added some new effects to shine it all up.
