Having some issues with this subreddit for a while now.

Whenever I post something, asking for advice or critique, I either get tons of down-votes with no explanation or very non-descriptive critique ("bad", "weird", etc., which in the rules is looked down upon.). I would really like to know how to get better, but it seems people just up-vote and down-vote what they think is pretty. It is disheartening. I am not sure what to do, for I do not have art friends IRL that I could ask critique of.
