You could also possibly reduce the character spacing, as right now the logo looks a bit disconnected.. And maybe rethink the font as well, try out a few more professional alternatives.
Other than typo, IMHO the additional textures and lighting effects are not necessary in a logo. What would happen if this has to be printed on a low budget? If it's printed on a one color offset machine, it would be a major disaster even at larger sizes. Printing this logo in large quantities (i.e. through offset) and at a high quality would push costs through the roof. Maybe you could think of recreating similar texture/lighting in a vector format with just one color. By one color I mean no shades or tints of that color either, just one single color value on a transparent or white BG. That would make the design a lot easier to work with in print... and for videos and other such things which can easily reproduce details at a high resolution, the current logo can also be used.
I hope this helps
