So many great artists I have worked with... I would reccomend most of them 
But I would suggest someone look through my dA gallery (linked below) and find the arts in a style they like and look further into that artist themselves as everyone likes different styles and such.
Still, as this is kind of a recomendation thread, I will toss out a few I continually go back to for more:
Europa777 http://europa777.deviantart.com/
Dingodile24 http://dingodile24.deviantart.com/
The_Hand http://the-hand.deviantart.com/
Jazzcarmona http://jazzcarmona.deviantart.com/
Taclobanon http://taclobanon.deviantart.com/
Avionetca http://avionetca.deviantart.com/
And a few I recently found who I am loving muchly:

Ohh, me likey! Thanks!
So, with Christmas and all the christmas money it brings in, I'm deciding to get some new art of my characters both in City of Heroes and out and I was wondering if anyone could suggest me some good artists to commision, and I'll suggest some.
1) http://dfreak235.deviantart.com/ She is a friend of mine and a good artist for some of your odder characters. Multiple arms, aliens etc, her specialty and she does them for very reasonable prices.
2) http://www.ahiddenlittledoor.com/comix.html Another great artist. Check out some of his comics. He can also do canvas pictures for you.
3) http://roonstown.deviantart.com/ Another artist with reasonable prices I like. He also does jewellery I think
4) http://lotusleif.deviantart.com/ She does plushies and they are so cute >w< She also does art trades
5) http://enigmaticthief.deviantart.com/ He drew one of the first pictures of my OC for me and defined her with her awesome hair, so maybe I am biased, but I love this guy. Gonna be commissioning him on her creation brithday :P Also a good artist of reasonable prices
6) http://daitou.deviantart.com/ Another friend of mine, and I list him here because people were posting about having a kirby dots aura. He does kirby dots for energy and I think it looks great. He also is a reasonable commission and a great guy for sci-fi or fantasy commissions because he can help and advice you on things like weapons and making them look realistic.
So besides all these awesome people who I have commissioned, anyone know of anyone good who is taking commissions, in the 5-15 pound range?
