I don't plan on making this thread a panatomime, so I'm just going to be blunt:
Your gallery gets low scores because they look like you've grabbed an image, and filtered-smudged the hell out of it.
This is your Legend Devil pic, compared to a pic of an action figure found off the net.
Everything in this pic lines up, from the abs right down to the low lighting in the right arm.
You didn't draw this, and I strongly suspect some of your recent stuff are also filtered up pics of stuff grabbed off the net, since they differ radically from your submissions.
