Not to rain on anyone's parade...but there is the copyright issue.
Elvis Presley Enterprieses has a very firm hold on E's image (not to mention to artist of the original composition) and they prosecute quite liberally. That's why velvet Elvis, at least new ones, have all but disappeared. Andy Warhol had terrible copyright issues with his similar paintings.
But congrats on the work...it's quite nice. BTW, the problem is with the left eye...not the right. Look closely, b/c he's snarling, the left eye is partially closed like he's in the process of winking. The bottom eye lid should be higher in the middle not lower. The cheek is pushing up into the eye.
