I’d say your pictures are fine. If you want, we could pull each one apart. But that’s true of any picture.
You’ve titled this thread website feedback, so here’s my opinion of it.
It works well and navigates easily, but many of the pics don’t fit layout.
The first pic, girl with umbrella looks to tight, the second pic guy with sunglasses look awful as the menu bar goes right through his eyes.
In fact the menu bar wrecks a lot of the pics.
Some of your pics don’t seem sharp enough for such a large display area.
But my main concern is that you seem to have only “life style” content. This is usually one of a selection of services offered. I can’t help wondering if it’s too niche a market?
