You peak when you peak!!
As long as your eye sights ok,, there is nothing stopping your batting improving season on season
Work on your core fitness,,hugely important once your past 25 or so, as that's when the injuries seem to occur a little too often
For me. I relish every season starting, always try to improve an aspect of your batting, even if it's just running between the wickets
I try to introduce a new shot every year,( not saying I play it,but I try)
As regards being new to the game,,,so what, I've played fairly competitive league cricket,with guys who took it up only in retirement
Main thing, is watch and learn
Listen to all advice given, and work out what applies to you
If you think a bit of coaching might help, then go for it
I'm 47,,and would love a bowler to tell me I'm past my peak!ha
Just don't mention my fielding tho
