3.22 Icicle Mine Saboteur

good afternoon friends!
I decided to make my own build for the first time in my life.
But I'm not sure if I did everything right.
Can anyone more experienced take a look and point out the errors?
thank you in advance.

the concept is this: an inexpensive and cheap build, not for uber bosses
