I would just loosen the letter spacing a little on your original and keep the original leaf but just twist the 'f' a little so it stems from the base (point) of the leaf shape - that will hopefully differ the space between that and the edge of the leaf (so its not consistent like it is now) and hopefully lose the 'pigs ear' effect!
The clashing of the r and t really jars for me. Have you thought about the kerning in there â€” they're the only two that kiss in any of your options. Alternatively you could draw a very subtle ligature for them, just to make the shoulder of the r flow more naturally into the crossbar of the t.
I like the first logo (original post) and the modern leaf design you have on there i feel works the best with the typeface. I think as another member mentioned, its the f shape inside the leaf that needs little tweak, mayb curve the f so it follows the shape of the leaf a bit more. Dont think its far off tho mate.
Think you could keep the detail of leaf 1, but with the flowing shape of 1 of the leaves in design 3? Easier on the eye where its not so sharp and resembling a holly bush.. The weight of your 'advertising' text could be slightly lighter maybe?
