for a first sig its kinda appealing. For starters lets not use as fancy text simple but good looking text, also that is a bit hard to read. Some times you dont need any effects on your text and it still will look really good. Besides text lets use the render as the focus of the sig its kinda off to the side and theres alot of blank space probably shifting it in the middle would be a bit better. Learn what c4d's are these are very helpful these give it the pop the explosion, the fire that makes it look like it has a good effect to it. A c4d is is like and abstract crazy render that can also make your sig look like it has flow, Keep trying look at some tuts and never give up you can only get better have Fun!
