Do I look cute in the picture (one in the red ) I'm 17... Too much?

For many years ever since I turned 12 I have never liked myself I've always thought I had a terrible body but in this picture I kind of feel okay but at the same time I think there is just so much I could fix about myself I look really happy and glowing and I wish I looked like that all the time some people said after I posted this on my Instagram page that I looked a little too slutty .... Is this too much do I look okay?..
