If you do want to be taken seriously, illastrat, it might help to first edit your post. Simple spelling errors certainly don't lend to your credibility as an advanced painter. Also, if you feel that others need to have an art degree to critique your work, perhaps you should have one as well to claim that your work meets the expectations of a particular time period.
Furthermore... should this style truly be what you love and are passionate about, then it shouldn't matter what else is on dA. Create your art and if others like it, they'll comment on it and share it. If you would like to improve your art, then ask for critiques. If you don't care for other people's art, then you don't have to visit their pages. Simple process.
You can play in the sandbox just like everyone else without having to claim that your toys are better than theirs.
I wasn't aware that dA catered specifically to one type of art over another, that would seem to me to totally contradict their mandate. The amount of manga & digital art would seem to me to reflect the artistic population at dA, & their preferences, not dA's. I find it sad & a little ironic that you would complain about dA catering to a specific type of art, then turn around & suggest that they cater to the type of art you prefer- and based on your example, your art specifically. Where would that leave all those manga & digital artists? And photographers? And sculptors? Graphic designers?...
