As it stands, the pair "Ti" is badly kerned: the top bar of the T is uncomfortably close to the tittle on the i. (The following screenshot is taken for text with dlig, ss01, ss05, ss06 and ss07 [TeX options Ligatures=Rare, StylisticSet={1,5,6,7}].)
Solutions could include:
Using a thinner version for T
Redoing the kerning (not a good idea — the bases get too distant from each other)
Moving the tittle
(the cool option) creating a fun ligature where the tittle is actually incorporated into the arm of the T
