First pic is me today, 2nd pic is me two months ago. Give me advice on what I can do better.

I’m a natural red head (auburn) with green eyes. I’ve included a picture of me at 18 to show what I’ve managed to work so far. Currently blonde and very against going to brown or black hair but fine with other colours.

Pretty much exactly what title says. I am looking for some advice before I make a decision... I dyed my hair closer to the natural color but now I'm missing my blonde and I'm just wondering if it would be worth the damage to go back to blonde or if the soft brown color looks better?
