here's a case where OP appears to want honest appraisals, which is refreshing IMVHO.  I liked the blue flame covering the hands. it would make a good tattoo with some simplification and clean-up. I didn't think it was a professional-looking toon because:

• overall style is primitive, done in isolation from others (no professional training nor art school)
• too symmetrical
• edges rough, machine-generated
• inner details blurred or tentative, afterthought, machine-generated
• awkward poser4-style kneeling pose with knees off the ground but toes touching
•  breast-lines and nipple positions like that are what we always see in primitive (unschooled) nude drawings of girls
• it appears to be a female but it also seems to have a beard
• no background, foreground (unless it's sposeta be a tattoo, in which case none needed)
