Not far to go!!!
Probably get some differing opinions but here's mine.....
Secret will be not just in what you eat but when. For a starting point your listed typical day looks pretty good. Some suggestions might come based on where in your 5-meal cycle you're working out.
Mantra that has been working for me (and gotten just a bit more abs that you have in your photos -- after YEARS and YEARS!!), eat for what you just did, or what you're going to do.
So first question really is, why the protein powder? I'm going to guess that BR is a banana smoothie?
After sleeping and getting ready for your day, assuming its a smoothie, I'd say add more to it. I find banana really takes over the smoothie so chucking in some kale, some chia, some hemp maybe and whatever other fruits you have -- will always taste like a fruit smoothie but with the added micros and fiber.
with all that written, then relooking at your post, sounds like you've got that covered in your AM snack...haha.
My BR currently is breakfast bowl, usually containing oatmeal, steelcut oats, chia-sometimes, berries/fruit, almond milk, sometimes a bit o'coconut oil. Filling, balanced for my usual morning at work. Alternatively, will cook up some quinoa w/lentils, peppers, onions, maybe some lightlife sausage, seasoning..eaten alone or sometimes w/toast. Keeps well too so you can cook up a batch and have a few meals out of it.
Like you, I don't count calories either.
What I found to really break out my abs was adding into my weights and cardio some intense full body workout (i.e. fighting). Hits my core from all angles functionally with kicks, knees, grappling, punching (rips shoulders too!), etc.. Keeping everything else the same, this is what did it for me.....mixed in with some planking, israeli situps, kimora situps, .....
So, for seriously ripped, fighting (think Krav maga, or muay tai, probably even some old-school boxing would work) took it to the next level. Getting to some parkor (spelling that right?) or some Spartan type of workouts would probably work too. Running 3-5 miles no problem. Biking too. Weights. Going 1:30 to 3:00 min rounds sparring kicks ass as it works strength, endurance, cardio, core and your brain all in one intense go.
And if into podcasts...check out Rich Roll (vegan ultraman) and currently I'm into Mike Dolce who trains MMA fighters for UFC and talks a lot about pre-fight leaning up. Non-vegan, but principles seem sound to me for daily living, eating clean, and timing of right nutrients before/after workouts....
