Crazy Ivan taught me a good way to get these leafs to look good and to forge well. Start off by giving your stock a nice point flat on the face of the anvil. Second, you'll put the tip over the edge of the anvil and hit it half on, half off (if I remember correctly) to give the leaf/head some defined shape and separate its shape from the stem shape. In your last picture, see how the back of the leaf sort of folds on itself? Avoid this by taking your hammer at a softly outward (toward the head angle) and tapping/pushing the metal forward, giving it a sort of forward sloped angle. This stops the metal from bending backwards on the stem when you hit it straight down in the future. Not to go backwards, but when defining the head make sure you hit on 2 sides (picture a square [ ], you want to hit on top and right side) rotate every good hit or two. This keeps it consistent and your stem won't drift on you. Over the edge of the anvil separates the leaf from the stem and hitting on two sides makes the leaf kind of triangle. It'll look something like an arrow head, high in the direct middle. From there, you'll want to shape the stem - make it as long as you'd like it to be, and use the leaf head as a guide - aka push the 'leaf' head over the edge of the anvil and pull it back until the defined edge is against the edge of the anvil, holds it pretty nicely. once you've got your stem squared off and at the length you want, you can shoot for forging the leaf itself. Set it flat on the face and hit at the high point, driving it down in the center and pushing the iron outward away from the center of the leaf. This spreads it out and gives it some shape. Once you've got that down a bit, you can switch to the cross pein and use it from the inside and work the steel outward as thin as you want the leaf to be. I'm still learning this myself, so I may have missed some important detail/step - or even got this slightly out of order (this was all from off the top of my head from a recent lesson) but my first leaf looked a whole lot like a leaf. Hehe when you're taking square stock to round for the stem (if you are), takes the 4 sides and hit on the corners, flat. This will give you an 8 sides stem, then do this again to make a 16 sides steam, and then gentle hits to round it the rest of the way. Aside from that, a few notches around the sides and some chisel detail and you'll be looking at a leaf. Personally, I flipped mine over and gave it some wavey shape with my ball pein, which looked pretty decent. Honestly, you've been doing this longer than I have - so maybe I'm not the best person to give advice, this is just how I was shown! Haha. Hope it helps even a little bit. :]
