I have often found in life when people put down others it is usually a sign of insecurity and jealousy..kinda like pumping themselves up by making others feel bad..nice quality!
It doesn't matter how you create art you still need to have artistic abilities and a sense of composition. The internet is full of awful images.. all the programs in the world "don't make an artist".
I use Poser.. I am on about a third grade level. I come here and marvel at the images created. Some of them are breathtaking.. takes talent to produce something like that.
Don't let snobbish comments upset you...apparently some have an inferiority complex and are willing to share it.
