Knife Game Asset

Tris: 6,878
Textures are done in Quixel Mixer because I can't buy Substance Painter right now.
I think that the model it's quite ok but what I'm seeing is some problems with the normal map from the high poly to the low poly. The main problem that I've found with personal critique is presentation.

Do you know a course to get better in this aspects?

I'm quite a noob in 3D so I'm sorry if my problems may seem trivial but it's a couple hours that I've tried to improve this render but I've not got any better. Sorry for the bad English, too.
