There are several drawings of the LBT characters as grownups to be found at deviantart. I don't think I know the artist of this one, but it sure looks well done.Here is another and again I do not know who the artist is.And another one done by WeisseEdelweiss, a member of the Gang of Five who has regrettably not be seen in ages.I'm quite sure there are more pictures of grownup LBT characters on Deviantart, just take a look and I'm sure you'll find more.
Has anyone seen this art before?some guy is doing a Land Before Time fanfic of them grown up and would you look at his artamazing http://theblazinggecko.deviantart.com/gallery/
