Hey Tash, good job, i noticed your using a wire trace line.
might pay you to get rid of that and use some fluorocarbon or even monofilament leader for your estuary fishing.
bait flows around much more naturally plus its harder to see on a mono/flouro line (Obviously not as strong as wire) but Should get you some more action, gotta get them to eat before you can catch them hehe.
not sure what rod, reel and line your using but 6-8lb braid as mainline with 10lb fluoro leader should be fine. If your reel drag is set nicely (not too tight) you should be fine 99 percent of the time.
Lee.
