C&C =) One of my first sigs.. this was made using gal's "H A L O . T U T" PS, the render's from Elder Scrolls IV: Oblivion. Be nice =S
Its not bad for being a begginer. The bg is pretty nice, but the render needs to stick out more. Try putting the render ontop of all other layers so it sticks out more. Also, try duplicating the render and setting the "Render Copy" layer on screen and lowering the opacity to about 50-75%. You can also go to Filter>Sharpen>Sharpen to make the render stand out more also. Keep folowing tuts and you will get the hang of it really fast.
