yea for a fourth sig this is great. try dulling down that bright white light. it's a bit tooo glowing.
The effect sin this aren't bad, but i think you could use a bit more blending over the render. try overlapping your effects like the lightning and the other glowy things overlop of the render. That'd help it a lot.

text needa a bit of work though. In general try to stay away from blending options like this. I also reccomend reading my text tutorial, it might help you a little bit get your bearings on text.

Not too bad overall. For a fourth sig this is gold. GJ
