This is your first so I won't be too harsh, idea is nice, execution is well... poor right now but everyone has to start somewhere.
all I see is a bunch of orange squares instead of actual explosions ... you said you've made the mod in paint, not the best software for modding, I recommend getting something lil bit more pro, either GIMP or Corel Paint Shop Pro, both are almost equal with few exceptions.
Also you need to get to know how xplosion animation works, what appears in your mod is random pics of shockwaves and explosions ripped from movies.
