I totally agree in your "art is subjective" comment, as such, my views here are just that, personal opinion, but I do disagree with:
"To date I have not seen anyone on the forums whose art or experience credentials and resume as an artist in the professional gaming industry come close"
Theres some amazing artwork showcased in cocos2d games mentioned on these forums (& more specifically character design, as this thread was originally about). While I agree your friend is certainly good at his area of 3D, theres a whole range of different illustration styles out there, and especially for 2D focused games, the 3D style may not sit right with them.
While there should be no problem with you promoting your friends work & skills here in an appropriate manner, your tone & criticisms came across a little harsh, and perhaps a touch misleading. As there could be quite a long list of very skilled people on these forums, equally as good, if not perhaps better at producing their own style of work.
I don't mean to fan any flames either, and wish you & your friend the best on any projects you do.
