What's the difference between "な感じ" and "という感じ" when written after quotation marks?


`な感じ` was crossed out and replaced with `という感じ` in a sentence that I wrote
that was similar to this one:

> その文には「それは私にはもったいない」 ~~な感じ~~ **という感じ** があると思う。  
>  I think that sentence has a feeling of "that's more than one deserves."

marks?




`な` is the attributive ending of a na-adjective or a noun. The modifier to the
noun `感じ` in your example ends with `ない`, which is an i-adjective, so it
should not take `な`.

As Flaw comments, `「～ない」感じ` is generally possible, but that has two problems
in this particular case. First, `私` will not work as intended. You can use
`自分` instead. Second, since the description in the modifier is is made from a
non first-person's perspective, it is more natural to insert `という`. You can go
with either:

> その文には「自分にはもったいない」感じがあると思う。
