I love it. The Colors, the characters, the render, everything. Text is just a bit hard to read. Might consider moving it over to the left a bit?
The colours are nice, but Tifa looks so out of place there. It reminds me of old movies on a green screen, where you can very obviously see they don't belong there, try and get her to blend in with the background a bit more, also move the text slightly left, so it's off her character model and it'll fill out the void on the left.
I think it looks nice, although the colours are nice I don't really see the deep purples with Tifa but that could just be down to my ignorance. I think the text works really well, imo I don't think you should move it as it'll take focus away from the render. The flow you have going works well but as Vivi said I think she needs to be blended in a bit more. For example, there is a white outline on the left side of her head which makes it stand out a lot and it could be improved wuickly by either removing the line or blurring a bit or general blending into the background. I love your work Amethyst, I look forward to seeing it each time, keep it up.
