SciFi and Fantasy Art: Colored siren

If you want to do anything to the background, I'd personally sketch in some vague dark grey-blue shapes in the background to give it that underwater atmospheric perspective. Otherwise, it looks just fine as is I love the tail.

Oh she looks wonderful methinks. The coloring is great, and the tail design is wonderful. Glad to see you've colored this one.

I like the sharp character contrasted with the blurry sea, and the coloring is pretty good too.

So creative. The tail is beautiful.

Oh wow, gotta love the tail..

Ah-ha! But the tail is vertical and I like to think of mermaids (actual mermaids) as a full-fledged mammal... so it really should be horizontal, souldn't it... Just kidding...

i liek yer version of mermaid taild better then other peoples..its unique..heh im odd i know...

The design is very nice. I think I preferred the uncolored version for one reason - while the body structure flows smoothly from fish to woman, the color doesn't. The sketch looked very smoothly entire - this is what she's supposed to be. The abrubt change of color makes her look like a grafted half fishy + half woman.
She's just suddenly green (or peachy, depending on if you go from the top or bottom). As careful as you were to have her body flow smoothly, you should extend that same care to the coloration of her. You might also consider that as a merperson, she might not have a caucasian human hued torso - maybe her torso is also green?

ummmm, the tail is good, but the body is a little too...stretched. It looks like you drew it in a hurry.

I like her 'tail' or whatever you may call it...
