Been drawing Phineas and Ferb stuff lately! So why not show them? Isabella's "grown-up" design comes from the fanarts of the girls I mentioned in the post "Marie in Dust".The ones of Isabella grown up come from a random idea I had where she meets Phineas as a kid (he went forward in time, though I hadn't thought about why/if it was an accident) She tells him not to tell Isabella, because the outfit she has on was one Isabella thought of when she was younger. She felt it would give away the fact that Phineas and her are together if Phineas told (younger) Isabella he saw her dressed like that. The reason for not wanting her younger self to know was basically not wanting to mess up the future. (a lot of jangled up time stuff)
The other fanarts are just random. :D
