Modelling my character concept

The modelling for this model wasn’t too hard since it was simple and I made the suit by using a human asset and inflating and using the fabric tool to make it look wrinkled and baggy. The rest of the astronaut like hand, feet and helmet are just simple shapes with little to no sculpting.
Texturing
For my textures I followed a fabric tutorial video to get a texture similar to a rough astronaut like texture I had in mind. This is a YouTube video by 3D Punk – Lessons:

Im only using 5 textures on this model and the main two being the fabric model for the suit and backpack. The suit material is basically the fabric material I followed from the YouTube tutorial with some changes to make it look less like a sweater and more like a rough suit. The backpack is completely different to the suit with a more coordinated pattern and a lighter colour. The rest of the textures are really simple textures I made such as rubber metal and tinted glass.
Thoughts?

I was happy with how the texture came out in the end, looking back at it now I wish I added some cracks to the helmet as a personal preference, since I feel it would fit the atmosphere of the game.
