i looked at the hr ....
btw , try to add a tiny bit of grain on brushed parts next time
the trick is and this is importnt to give it grain , then edit grain and lower the opacity so they kinda look like tiny microscopical specs witch you cant really spot in small size ..
also your brushing looks tight maybe it's a bit to neith , you know not everything has to be perfect paint wise , try to play with a dust spec here and tehre
its hard to explain in words but if you take this brush style and perfect it by making it less perfect (i mean the paint itself)
also some very thin selections with the feather set to 1 (for instance) and lightened and darkened can helpgetting paint alive (for everything i mentioned dont go crazy and overdo it)
some more shading like on the lower parts of the car it can be darker as higher places (this also go's for body edges) a lot can be done with the burn and dodge tool
most things i said here are just hard to explain , hell every time i brush i just try things untill it look the same as some ori parts or i match everything together
what i', trying to say basicly is your brush is great now try stuff like mentioned to get realism in there
i also like your eye for lightfall and colors and the way you took the sunlight from the bg and made it run over the new brushed front (stuff like that is exactly what i mean that helps realism)
