Like Ghost said, nice first fly. THe head should be about 1/3rd the size and leave some bare shank between it and the eye. The tag is lumpy. I also think you tried to put too much on a small hook. Maybe just two body segments. The herl is not dense enough. The tail is too long. There is something yellow at the front of the butt? There is only one butt, the rest are called joints. There is something shaggy on the rear two body segments??? There is thread showing from the tie in of the throat rear of the head.
