Are you sure this is a twinkle?
I have one in bloom as well right now and my leaves look a lot bigger and more open then your.
beautiful growing btw
I'm just going by the tag and the fact that I got it from a grocery store where there were many other Twinkles. I think it is a common one to be sold in box stores. It could be different culture. I grow in a greenhouse that is quite hot and bright in summer and quite cool and dull in winter. I did snip some leaf ends off and my leaves are about 3/4 inch wide. Maybe the photo angle has something to do with it too?
