Corrected entry: In the third story, "A Lover's Vow", Carola tells Preston that she was able to get his artwork exhibited at a very prestigious art gallery. At the end of the story, it's revealed that Carola is the very gargoyle that killed Preston's friend and swore him to silence. A very big mystery how a gargoyle, posing as a human, would have any connections to an art gallery at all.

Correction: This gargoyle is a supernatural creature. Who knows what kind of connections it might have, or what kind of powers of persuasion it would possess in human form? She's with Preston to make sure that he wouldn't reveal the secret, and when he doesn't she rewards him for not revealing its existence by making him a successful artist by using her abilities to make it happen.

That's what makes it a plot hole. The only known ability is being able to become human. There's no way of knowing if she has other abilities such as persuasion. It's mere speculation.
Maybe, but since we know nothing about the gargoyle one can argue that it's a potential power it possesses. Another possibility is that Preston may not be the only one it has an agreement with. It could very well have other people in the city that saw it at one time or another (we don't know how old it is, after all) that promised not to tell and theoretically that could include people in positions that could help Preston (museum curators, art critics, etc). So there isn't really any plot hole here, just a requirement to stretch one's imagination.
