Well, text should be a bit close to the render and should find better text fonts .
Try adding some lights on it so it could look much much better and more effects, render doesn't have much going on, background has more , for the size, is great as it is.
Since is your first time and you made it with help which is a great start for a beginner . i'd give you a 6/10. Great job!

I'll put up some great resources for anyone who wants to learn later on.
