Here are some photos which I have taken at the Prudential Marina Bay Carnival 2018. What do you guys think?

It's a fun, colorful location.

3rd image looks soft or out of focus.

Would you have been allowed to use off-camera flash at that location? I feel that a quality light in a large softbox would've really helped put the focus on your model with nice clean light and really make the images pop.

You've managed to achieve the quality of a full auto shot,  processed in a mobile device app using a preset filter.

Congrats!

I think they're snapshots at best.

I like the first (and duplicate fourth) image. It's colorful and the model is relaxed and natural.

That third image, in addition to being out of focus and badly framed, is just contrived and forced.

they are all a color riot, if that is what you were after, you got it.
most look like fairly wide lens, but 2nd shot's distortion make
her shoes look giant.
