What you did with the text only looks cool if it doesn't take up the whole sig and if the fonts aren't horrid, which isn't the case here. The BG is nothing and the picture is way too small. Maybe your worst.
It's definitely not your best. The text isn't that great either. But also, when you do sigs, try not to have the text running into the pic. You got the word Legend running into Lebron's face. You should move the "Future Legend" text over to the left more.
