First Mini Completed! Feedback welcome before I start my next project

I completed my first mini recently and made my first attempt at photography (I think I prefer painting) but it was a fun journey, any feedback is welcome before I start up the next project of some Krieg Combat Engineers. Looking closer at the photos I already see tons of room for improvement on doing more layers and pushing more highlights but a good start I think.
