Beck

...then you might like
Ashita no Ousama
|
Despite their differences in protagonist age and target audience--Beck is for and about teenage boys, Ashita no Ousama adult women--both manga follow slightly dorky, down-to-earth main characters growing up and learning to follow their talents in creative fields. Both of the series show realistic ups and downs but maintain a basically optimistic tone, and both also have a nice but mostly background romance subplot.
If you liked
Kodomo no Omocha

...then you might like
Ashita no Ousama
|
Kodocha focuses more on romance and comedy, and Ashita no Ousama shows more of the details of the acting world, but both series are about strong female characters pursuing careers in show business. They're both well-written stories, cute but with enough emotional depth to keep them from being fluff.

Nijigahara Holograph
|
Both are fascinating, somewhat confusing trips through the worst side of human nature and its violent collision with youth. Insanity and the paranormal element are important in both stories, with a blurry line between them.

Suna no Ue Rakuen
|
Two underappreciated works, Suna no Ue Rakuen is a collection of short stories and Adult's Problem is a single-volume story. Though they have few surface similarities, they're linked by the author's excellent sense of characterization and by the themes of family ties that occur in several of the stories.

Saishuu Heiki Kanojo

If you liked

Seimaden

Both stories are about the reincarnation of troubled love and the questionable value of "holy" gifts, and both have some very nice art with similar ornateness.

Pietà

Similar themes of two people helping each other cope with their various past damage, although Mars is a much longer story.
