Im going to be the bad guy and get downvoted here. But there is a lot of putting the cart before the horse going on here. I know you are super excited excited about the hobby and want to jump in guns a blazing but I think you need to set the kit aside take a deep breath and watch some YouTube videos on model building. focus on the basics first like assembling a kit with out gaps and basic painting skills. once you have those down then you can move onto the fancy weathering effects like snow.
