Well the lettering can be fixed, thats no problem. I thought it looked a little strange with the outline on the lettering, almost like an inset, when the text is more on the exterior of the speech bubble.
The glossy on the other hand I feel is OK, and was intentionally included. Its an object (bubble) that is intended to be glossy, not matte or dull, so the lighting should reflect that. Other icons on the jimmac's page are similar.
