It is a really good drawing. The tattoo DOES look really cool. Adding a background would definitely add to the story of the character, and even improve what ever mood you intended and would make the image look more full. Keep doing a good job man :)

Dat tatoo...awesome. And as the character itself is really well made, even if the eyes could get a lil more detailed. But i like the shadows and the form i kinda wish she had a bg storyline. keep up the good job

i really like it :D ... but i would really love it if you would add some background
but still nicely done :3 specially the tattoo
