Yup. Blend it better, put more effects and that random blur on the sword ain't good. Text could use some work, too.
The render has a red hue on it which gives it that feeling that you just pasted it over the background with no effort (which is prolly what you did since it's your first, that's what i did). I would maybe fix that with some photofilters, if you know what they are. You could also use some effects in there to make it less boring. The text is just a little too attention grabbing. You want it to be bold but subtle at the same time.
