I agree. Yes, digital pieces have a lot of aesthetic appeal. The tools used to create them are limitless, and they can capture colors and textures of any kind (where traditional art is more limited). Not to mention the idea of animation, and the appeal of the smooth, modern look. But Deviantart does seem more focused towards digital art, which has its own section in the forums, and makes up the majority of art on the site.
As a traditional artist, it is a bit discouraging.
As an artist who uses both does both traditional and digital. I find it depends on the piece I'm working on. What kind of feeling do I want it to have? Traditional pieces (or at least mine) tend to have a more rustic feel while digital is more crisp and clean. Though I can easily say I have far more fun with traditional XD. With blending multiple mediums and just playing to see how it comes out.
With digital art there's a lot you can do using computer filters, but some people consider it cheating. I think traditional art is amazing, since I suck at it, so I really respect the people who spend a lot of their time working on a piece, though us digital artists work really hard, too. But, it does take time to get used to drawing digitally. From using a tablet, to finding a program that suits you.
well when it comes to buying stuff. With traditional you have to ship the canvas or painting to someone out of your area, so in general its way more pricey and originals tend to go for more money and your market is more limited to people who are willing to spend money for original traditional work. With digital it can be easily emailed. So the convenience of digital can be more appealing when dealing with people out of state ect. For someone buying it..
Dont worry if your not getting hits to "sell" things....at this point you shouldnt worry about selling stuff but focus more on developing yourself and getting better as an artist. thats when youll be able to really sell stuff and make some money. Till then ..practice.
One of my illustration guest lecturers at university said that the best thing to do as an illustrator is to work traditionally, because illustration is about prints and copies, so you take a great photo of the original and that goes to the client, but since you retain copyright you sell the original as a piece of art to the people willing to pay the money and make twice as much. With digital you don't have a physical copy to sell so you will always be selling a print or a copy.
Having said that I work digital traditional mixed media so I still have nothing physical to sell XD
