small explosion sprites

small explosion sprites

I am currently working on a space game where you fight off enemys to progress to the next wave

 

however I need sprites for an low resolotion pixel explosions

 

I want to sizes 8x8 and 16x16

I would like the animation be based off of a very vary pixelated cloud(no not the stereotypical shape) topdown explosion

I would like it to start from white, yellow and orange to a orange, red, and dark red and then to a grey drakgrey and darkergrey cloud

this tranision can be up to 16 frames
