How can I improve my French accent?

EXPOSURE!Listen to French radio (there are plenty of apps for that).Watch French films - if you struggle with comprehension, stick on the French subtitles. If that's still to difficult, turn on the English ones, but always push yourself to catch those pesky phrases that escape you (remember you can pause and rewind!). Find a French conversation buddy. Listen to French music. Christine & The Queens is a personal favourite of mine.Talk to yourself in French, repeating the sentences and phrases you have heard, imitating the way they were spoken by natives.
