nice job for a second sig. you've got the idea.
-i'm not a big fan of sigs 468 pixels wide, especially when you've got a bunch of empty space.
-hall looks a little jagged on the edges but i just finished a video tutorial on cutting players out so hopefully i can help you with that
-the text is nice, you might want to try some blending options (right click layer>blending options). i personally like white text set on overlay with a 1 px drop shadow at 1 px distance, a white color overlay with lowered opacity, and a black outer glow set on normal. but of course, that's just what i like to do
other than that, nice job, especially for your second try. and oh yea, might wanna stick on a border
(new layer, select all, edit>stroke>1 px black
