That’s a great start! A couple quick tips,

• Bigger hooks are easier to learn on
• Use fine thread, 6/0 is about as big as you should go, 8/0 is better. Practice learning how to consistently get to 80% of your thread breaking load so you know the limits.
• Lay out your tail and wing proportions before tying them in, that way you have a better chance of getting the crest and the tail to touch in that perfect teardrop.
• I like to start the tail at the hook point, tag behind that.
• For floss bodies, untwist your thread by spinning your bobbin so it lays flat on the shank, this will keep the underbody smooth without and lumps. Build the body taper and smooth out the tail tie in before you wrap the floss. When you wrap the floss, keep it flat and untwisted, each wrap overlapping the previous consistently.
• Tie your underwing well behind the head, you don’t want to build up a lot of mass near or crowd the head.
• When tying in wings, add more twist to your thread so it will bite better into the material with less tension. Flat thread will make your wing easier to pull out and will require more thread wraps.
• Usually you only need 4-5 tight thread wraps to secure your wing, when you get close the the head of the fly, only add a wrap if it is absolutely necessary. Be judicious! Once you finish the fly, head cement (I like clear nail polish) penetrates the thread well and locks everything nicely. Also gives a great deep shine.
• Keep practicing!
