I cannot say what I like as sometimes I just ... like. And while being 'good at arts according some code' resulted me to have good feedback from tutors and people, but it wasn't me. So I rather have 0 favs, no support from tutors as long as the things I do is 'me'. So from others work I see that "them" - atmosphere and something distinctive.
You never can explain why you like something. I.e. when you look my "page" and my 'fave' to introduce my gallery is a photo made after i placed camera on floor to tie a shoelace. And then someone offered me handful of cash to buy it out. Its a failshot, yet it's been offered such amount of euros that I found it be crime. And then i have there a work I spent hours, hours and more hours to work on and eventually i was told its worse drawing i ever done.
I stopped thinking about others, people and just do my thing. Even when its just a scribble, stick figure or something outside the mainstream. Art's something you do to express yourself and not everyone needs to like your "opinion".
There's reason i still seek my style as I spent around 10 years on art classes and under hand of quite known (local) tutors and it took LONG time to understand that I don't 'speak' for myself. Lucky are artists who start off more independent and maintain their line.. even when it is, as i said, stick figures.
300 favs? Must've been another account. Anyway on dA -- it's basically kitsch, pop culture and stuff that appeals to the (uh) baser instincts that get views.
So, don't worry too much about popularity. The unspoken rule at dA is that the popular get more popular and the rest, well, just muddle along. For example, last month, I did a random survey of the Daily Deviations for over four days. 60% of those who received DDs on those days already had one. (And, some had 3 previously.) The remaining 40% who received Daily Deviations on those days had none previously.
BTW, keep up the good work. You do have a neat gallery. (Some of my students would be jealous of your artwork.)
