What To Do With My Hair?

Alright as you guys know I'm always so indecisive on what I should do next with my hair. For those who watch me on YouTube you should know about how pale I am, and I question colors for my hair very often. I recently dyed my hair Brown. Which I used Garnier Nutrisse Lightest Golden Brown for it. Which by the way I love but that will be a review in it's own.

But onto the matter I did buy a highlighting kit about a week ago and yes I do plan on doing but not yet I at least want to wait a month or two because my hair needs a break. Now to the question before I do highlights should I make my hair a shade darker only because I do want a noticeable look that I am putting blonde highlights into brown hair. So if I could have you're guys help with deciding that would be great! Please leave me opinions down below.

Here's what my hair looks like now:
