Nice work on the Gordon pattern.
The Bumble Puppy is a great choice for tying, I've been making renditions of them for a long time. The flies below were done about a year ago I think; really cool part is the fish here grab them as well as anything else.
You may as well have a go at feather wing streamers, that will keep you busy for a very long time. I've been making them for........ 45 years (I had to count) and still have some to go
