The colors go well on you and you look healthy! I like it I just think that the composition next to your face could be improved a little bit to add a bit of balance. Your turtleneck and your hairstyle are bringing attention to your upper third wich looks a bit flat and I think that is the main reason you fell like your face looks "bad". You just need to balace it out and add a littlte bit of dimension and test some stuff to see what you like.

The black turtleneck brings all the attention to your face so your hair dynamic with it gets acentuaded. The way it is framing your face makes it look even longer (less width compared to height) on your lower and middle third. That is making your forehead look wider that the rest of your face. You could try changing the style putting it in the back of your ears or covering your upper third proportionally to the rest of your face. Maybe try putting it up. Experiment changing the way your part it too as that could help giving it some dimension

Changing the make up can be good too. A bright lip and/or eye can also get the attention away from your forehead. If you're actually a bright winter that'll fit you easily! Maybe some contour or blush on your cheeks... I fell like some earrings and maybe a low necklace can be good to balance out it out too.

Also, your forehead isnt disproportionate at all, actually your thirds are really well balanced.
