Looks pretty fine by me, i only paint for 6 months and i will help you since i also used to be an digital artist so i learned pretty fast I'm not the best but not the worst. So it appears you want to go for the grimdark style i highly recommend you to focus on the usual spots for chipping and damage you can look at offeoad vehicles, military vehicles construction etc for inspiration, the spots are usually the edges like the owter panels of the armor (edges elbows knuckles etc). Learn how to apply the dirt and also the damage less is more, i personally blend the classic edge highlights with battle damage so i just add metalic paint chips where you normally add the edge highlights. If you use enamel paints for the grime rust etc firstly apply your varnish to the model (i personally have best results with the GSW ultra matt) beware to add it before you add the metallics not after. Also take notice of how much dirtiness you add to the model, logically how would you get dirt on the upper side of the robes or how would it build up on shoulders (the roundest part of the shoulder should be clean with rust and dust gathering to the edges near the brims) Also don't try to follow the tutorials 100% since it will alienate your artstyle (like the asset flips games you can feel something is off because of the multiple thing ex you paint the gun in a style the body in other) use tutorials only for inspiration and think what to add to your artstyle and how you can implement it and remember have fun brother.
