Awesome shot! I've never really done much with focus bracketing like the other user suggested (I really should), but I'd recommend getting a lens reverser if you enjoy macro shooting. I got one for like $15 on Amazon and thew it on my shitty kit lens and love it. It requires a lot more patience and focus to use, since you don't get any autofocus or aperture control, but it's a super cheap way to get some great macro shots!
