The problem with pulling images from different sources is that they all look like different art styles. IE, the clubs, ball, and background.
These suggestions might be tough without a real graphics software program:
The clubs need to be cut out cleanly, and the grooves on the heads should be cleaner instead of all blurry.
Clubs and Ball should be the same style artwork.
I personally don't like the font for "BNB"
I'm not sure why you lowered the contrast of the background picture, but i think if you toned it up and made it clean and crisp it would look "more professional"
