looks good, but;
- i think you can make it better by simplifying it. Get rid of the space within the letter( the counter).
- maybe making the edges rounded, that goes for the gap between the p and d.
- one directional lighting, so instead of showing light from top and bottom, maybe use only one and place it somewhere effective?
just my opinions

oh and i'd got with the diamond, caught my attention the most.
