It's a start!
I think you need to sit back now & honestly compare yours & what's in the book, so you can see what needs tweaking.
I can see you nailing it sooner or later, just going to take a few more efforts & abit of observation of details.
and to clarify- i'd never heard that the term implied anything derogatory, just a common 'industry term' describing the fat, round little roses typically used in this style. i think Bert's look just fine.
Not a bad "first go". You seem to have better outside work on the first pic than the second but your cinquefoils look better on the second pic than the first. Try to keep the petal spacing and size as even as possible.
With the roses, of you cut the centre part first i.e. the petals, any folds and then the top, and then join the bottom you can avoid making the bud too round. If you look at a real rose bud its more of a squat egg shape than it is round.
