No, don't worry, it's not bad taste it's just that many account are created on the sole purpose of "serial-fav" artworks, all the more that now people don't need to look at the page of the artwork to fav it.
Thank you for the favorite gallery, it's been quite sometimes that I'm on DA, I use it as a big source of inspiration (hoping to be able to do such things one day).
Speaking of which, I saw your last artwork on the "newest", and recognize that it had it's real special art style (which is quite rare in this section).
Your gallery is really interesting! One can see the many different style you tried and how you improved (I had the way-too-long-necks phase too
) and really fast, if I may. Your last two piece have really a different art style, seems to be a bit more yours.
I really like that diversity and your originality (when it comes to the charater sheets for instance). If you keep posting great artworks like those, I think that you'll find your public very soon.
