Noted. I've removed the work and will work on acheiving similar effects with a more linited pallete and dithering techniques. Will let you know when its up so you can marvel at how awesome I have become  Thanks for the critique 

If you're going to use tools like gradients and opacity effects, use a format that preserved their smoothness. Reducing the colour count automatically looks bad. If you need a small colour count and can't have the thousands-millions of colours created by those tools, then create the effects by hand, controlling the colours directly (the "pure" pixel art approach) - that'll look better than an auto-reduced image and probably result in far fewer colours.

On a related note: on PJ, only "pure" pixel art is allowed. While tools like gradients can be good additions to some pixel art, such hybrid work isn't allowed on PJ.
