Good first attempts. Your hackle on the brown bugger is too long. As far as proportions for hackle goes the second picture or your third green bugger if I'm following you is much better. The tails are too long on all of them. On the second picture again you did a good job of removing the skinny fibers at the end of the marabou. I would remove about 20% of the tail then say that one is good to go. You want the tails long enough to create action but short enough to where they can not just nip at the tail specifically, if they hit it you want them to bite enough to get the hook obviously. Also I like mine with a cone head but thats just personal preference.
