Welcome to the site polskaprince from the uk. You've come to the right place to help you improve your ABing, lots of great people here who will be happy to give support and advice. Looks like you are doing great. I agree with the post above, about working on your tones and graduated fades, and also maybe sharpen things up a bit, as it has a soft slightly fuzzy look, this could be overspray, or maybe you could reduce paint more so could work at lower pressure to keep things a bit sharper, and possibly add some textures. But I think you are doing really well!
