Portfolio and artwork critiques

Cr1s1s

So i'm currently a student about to graduate soon and these are some of the assets i have made during my last few months and put together recently, feedback either on the presentation or even the asset themselves is welcome. 

Here is my portfolio so far https://www.artstation.com/artist/talhashaikh

The tank is definitely the strongest piece! For all of them I feel like the texturing the needs another look. The Spec/Metalness should help define different material types and the gloss/roughness should describing surface of those materials.
I hope that makes sense

I do think i get what you mean, but could you elaborate on which pieces or parts of them stand out the most to you as not right?
