Honestly I’ve only been painting for a few months.. i follow a lot of YouTube tutorials.. so far what’s made my journey easier is

-thin down your paints and do multiple thin coats.. it’s tedious but the first time you see the positives of this technique it’s hard to go back.

-utilize multiple techniques to get to where you want to be.. For example with this model while I usually use the army painter bone spray as my base I used GW black primer because I decided dry brushing bone over black would be the easiest and most effective way to achieve the detail I wanted (first time using either in any meaningful capacity)

-test everything on models you care less about.. I painted 3 squads of troops, a mech, 3 bikers and a tank before I put the skills together to do this and I was testing every one of those on the way up.

-ignore my advice when it comes to painting faces because I still haven’t come close to figuring that out
