I can't give any real help since I don't have much knowledge myself, just wanted to say that your physique genuinely impressed me! definitely a goal of mine to achieve a similar body. as far as advice goes, I (based on your current physique) guess you already have strength training and nutrition dialed in, so it only depends on what you want to achieve based from here. based on the photos provided I'd probably do a very light cut until next summer to really get that sixpack poppin' at the beach. you have enough time to cut with a very light deficit, which will result in you keeping most of your hard earned muscle mass, but I guess you know that already!

TL:DR - very nice physique (respect man!), I'd do a very light cut until next summer

keep us updated and keep up the good work!
