mining construction sprites

I wasn't able to find any sprites i wanted for construction / mining so i made some vector ish sprites of my own?  I'll list some of the things here. 

1. employee sprite generator - so this is jsut random parts to put together some employees, i worked in the coal mining field so the uniforms / hard hats are based from that field. 

2. equipment - production hoe (excavator), loader, rock truck and dozer. 

3. i have some environmental tiles two seasons - winter and summer because you know thats the only two times that matter in construction / mining. 

I added some icons for a coal pile, a dirt pile and all the equipment. intended for icons.

i created a wiggle wagon and a smaller hoe (excavator) for the wiggle wagon. there is some parts in there also for the strip. high wall parts.  

there is a basic day and night back frop.

I couldnt upload the image of the strip digging the mountain away because its too large, it is in the minimap graphic you can put it together and see it in play. 

I wanted to build a idle sim with this and i never got to working on it. 

These assets i ask if you use them, even in a prototype please show me and credit me (i know there programmer art but ide love to see them in action).
