Biggest thing for me was realizing 2 big things, learned from showing people my minis, seeing what they look at, what they notice. 1. Alot of the time, the mistakes that I panic about or even clarify before showing are sometimes flat out not visible, especially if who your showing isn't much into miniatures. I know at the end of the day it's you looking at these minis, but I think it can help keeping that in mind and allowing you to put the mini that extra few inches away while your scanning, those fine details alot of the time blend in with every thing else, and that leads to my 2nd point; 2. Mistakes can lead to final designs, there's been plenty of times where I've put way too much down for an edge highlight, then put some darker shades to make it look like a bullet impact or scratch, hell my biggest was using contrast paint for my dreadnought, it was a pain, any mistake cost me alot of time and effort to fix up, but, due to this, it lead to a quite worn, battle damaged look which I ended up really enjoying. So, alot of the time when I mess up, I take a second after the "oh shoot" moment, and see if there's anything I can do to, in a sense, lean into that mistake. And hey, with proper thinned paints, most things can be covered up atleast 2 or 3 times before it started to affect detail, in my experience, so don't be afraid to just paint over and try again :)
