You'll get a good idea of how you'll age even from a relatively young age. I think you look pretty good, no older than 25. Probably around 23? The camera angle tends to not be the best. Having it more level with your head or slightly above is better.
Look at the Karate kid when he did karate kid 1 (he was 22) but played a 15 year old. Karate kid 3 he was 27 and still looked no older than 20. And my cousin Vinne.. only slightly older. And he maintained that for a long time. It's only recently his skin is a bit messed up... I can see lots of sun damage since he came back into the doing shows/acting etc..
You said you started doing stuff from a young age. What have you done? Do you have a personal thread on here about your lifestyle/diet/supp etc..
In our 30s is the time we'll really see our diets pay off (or not) I think. You don't need "decades" to see if something is working :p
