What I see is just a plain and solid CSGO skins. Those details, scratch, shadows, and lighting from the original texture are gone. I would recommend you to overlay the textures, adjust the opacity, to maintain the details. Don't just cutting the CSGO skin into pieces and slap them into the original textures.
You've often said that this is a retexture. Retexture means you are creating a new texture from zero, add some noise, using a hand brushing technique to create scratches texture and bake the shadows and lighting to them. What I've seen here is this is not a retexture. This is just copy paste and slapping texture.
I would recommend you to take a look at Teh Snake and Millenia's works to learn and improve your texturing skill. I know that you've already busy with school and real life, so just learn step by step, slow but sure.
Final note: Pay attention to quality, not quantity.
