This.
My first bugger looked more like a Siamese Fighting Fish than anything. The fish don't know that your fly doesn't look like Dave Hughes tied it. You'd be surprised. My son took a bunch of my "Round One Rejects" and he's been successful to the point where he won't let me strip them down and re-tie them.
That said, keep working at it. As you move on to other types of flies, you'll want to be more particular about the proportions. Meanwhile, tie that bad boy on and go catch something with it.
And welcome to the addiction !!
