They sound fine. no problems really. The first one sounds good, but here is what I mean.

That guitar riff being played, is not yours, you didnt write that. it was there in the software, so you decided to use it.

To somebody who doesnt know, it would make them think you wrote that.

Now, what if somebody else recorded a song with same chord progression and style? What would happen?

You would both have the same song.

THIS, is the limitation, it's all boxed arrangements, nothing belongs to you.

It can sound fine, especially if the singing is good on top of it, but it's as fake as a 3 dollar bill.

And the sound is not just the shapes of the instruments, but the feel.

But dont take it as a diss of your songs or ability, thats not the issue.
