Coot, that is one excellent looking shrimp imitation. I will be making some of those up for sure.

I've used raw prawns for a number of years, they hold-up very well on their own, but I like to cut the peeled tails into small 1/4 inch bits which I then tie up in red mesh netting. This makes a small dime sized little ball that I thread onto my leader usually above a smaller corky (I thread it on with a carpet needle) The shrimp-ball and corky with a little yarn in the hook's egg loop, has put a lot of fish on the bank for me.

There was a thread on here a few days ago, about the use of two corkies being better than one, but this set-up works even better than that.
I carry them in old plastic 35mm film containers, sometimes I add extra shrimp oil and the tight snap on lids keep everything neat.

You can also put any you don't use right in the freezer when you get home and they'll keep for several trips, just DON"T forget to take them out of your vest and put'em in the freezer at the end of the day, talk about STINK! after 3 or 4 day's you'll wonder what the hell died! if your married you'll really loose some points with the wife!
