This list was actually made in my old Gaia Journal. (:

I would have to say http://dragonnova.deviantart.com/.

Of course, I don't even have an account - I've done nothing worth looking at.

http://luc_iole.deviantart.com

i can't believe nobody's mentioned http://enayla.deviantart.com yet; though everyone does have different preferences when it comes to art, of course. i think she was the first person i watched on dA, and she still amazes me. She also does gorgeous skins for the Sims 2, on a random note XD

I like my pictures dark and sinewy and dripping like ink.

Someone here mentioned Artgerm.

Artgerm ftw. REPRESENT!

I'd have to say liiga, peachysticks, artoftheempath, and thedreamflier are some of my most favorite artists.

http://saimain.deviantart.com/ - for her beautiful flowing hair and wings
http://gargoylegoddess21.deviantart.com/ - for the beautiful style and coloring (and shes just so sweet)
http://bri-chan.deviantart.com/ - again love the style and coloring... and she always has such funny little mini comics
http://wen-m.deviantart.com/ - just wow
http://auroreblackcat.deviantart.com/ - ive admired her art since 2000
http://nati.deviantart.com/ - again.. i love her style

there are of course many many more, but listing them all would be such a very long list

Buninou

All of different styles. :D

http://katibu.deviantart.com/

• The inking and detailing on her black and white pieces is astounding.

http://kitanya.deviantart.com/

• I adore the way she colours, and she makes me not hate chibis...

http://loish.deviantart.com/

• Amazing stylized art... plus the way she draws hair and anatomy is just * 3*

http://purpleangelica.deviantart.com/

• Her art has a very stylish look to it, and up until recently it was all mouse-done. A close friend of mine~

http://tracyjb.deviantart.com/

• LACKADAISY CATS!!! She's ASTOUNDINGLY talented.

http://weja.deviantart.com/

StudioQube <---omfg professional grade art *3* Very cute style too. I kinda think of Gainex when I see their work.
http://studioqube.deviantart.com/

Feimo <---- I actually think her chinese novel style is better than heise's. Perhaps better isn't the right word...but if you click on her gallery, you'll see what I'm talking about. Her pictures are worth a second glance or 4.
http://feimo.deviantart.com/gallery/

Theo <---- I'm totally jealous...completely and utterly, of this guy's skill with drawing landscape and buildings. Professional grade and only 17....WTF, this guy is younger than me. XD
