I do not have capability to appprove a contribution, but this work is not a good one. Try practicing your skill in basic logo making before contributing.
See this:
- Glass Browser is not an android apps, it's for mac, windows, and linux.
- The combination is not quite good, it's more like an onion. More complicated than the existing logo.
- The logo color you provide is not quite matching, try a gradation of several identical color
Keep posting gan!
