Yeah, I know how that is sadly, it may seem hypocritical coming from someone who received a dd just today but on average, my works dont really get much attention either, including the ones I find some of my best.
I sadly dont always comment on things I fav myself, but at least sometime I do, and sometimes I just express with a comment how impressed I am about the given artist overall on their profile instead.
And I usually check out profiles of most people that fav anything from me just partially out of curiosity and part as a way of giving back, so no problem there
Its rough in here, overall, comments, and especially such that at least in short give any kind of feedback, are very rare except for people with really big amount of watchers, I have 170 watchers and I get like 0-3 comments on my new works, so there is that, go figure..
Long story short, if I continue submitting my works here, from a certain time its with a lot reduced expectations than it used to be.
And lastly, I feel like lately in this age, being really socially active gets you more feedback than actually being a decent/good artist, which is kind of sad.
Just my 2 cents, hopefully if you choose to be showcasing your works elsewhere you get some noticeable feedback, best of luck to you
