Use the 'edit it' under the art to upload a version that uses no CGFX or is entirely pixelart. You can also link in the description to this hybrid version as a link.
Pixeljoint is a gallery and showcase of pure pixelart so hybrids and non controlled pixelling is not accepted tho there is nothing wrong with them and many make them, k. Its just about preserving the artform.
Ah! sorry about that! I am very new to pixel art, I will fix this soon :)
What I was going to say has already been said. Otherwise it's very nicely done. :) I look forward to the revision.
