Good start, need more work.

It's a good start, but it needs more work. May I suggest that you put more time to work on the main parts of the gun first and then you copy and paste it and change some details so it fit another model, that's how I work. These are indeed good, but some parts are still too square-ish. The overall lack lights and shadows , you can surely find some tutorials on the internet to make you understand better how to make shadows and lights and it would greatly improve the look of the guns and how to make them feel like they were more 3D. Also, the wood textures would have been better if you added more than just a line, you could have added just some less dark tones around the line of the wood grain. Don't forget to get a reference picture of the real thing if you lack the information on how it's supposed to look like, it's not cheating , professionals do use reference pictures when they lack the information they need to make things look right. My comment wasn't to make you feel bad about it, You got a lot of potencial , everybody does, but you need to invest more time and effort if you want to improve yourself. Practice practice and practice is the key. I hope that I have given you enough tools to get better and I am looking forward to see your future works!

Sorry for my english,
