You've posted some nice artwork and asked for feedback, but no one seems to be offerring you any critiques. Why are they passing you by?
Someone asked me this in a private message. I thought it might help to share the response, and get more details from the community too.
I feel there are a couple factors at work here.
First off, there is a lot of traffic here, so there are a lot of things to look at, so not everything gets responses.
Next thing is, you might have a great initial post, but no follow-up posts. There are unfortunately a lot of people who post something, but thereafter they have no other interaction with the community. 1-post wonders.
Often these are seen by others as not worth the time to write a good solid critique, because it looks like a fly-by-night. You invest your time to write a good crit, but then hear nothing else from this person.
This doc describes a similar online community and why things are the way they are. Not exactly the same here, but shares a lot. Just replace "hackers" with "polycounters". Worth a read.http://www.catb.org/esr/faqs/smart-questions.html#intro
I suggest posting regularly, updating your thread with new work. Show that you are proactive and steadily working on your art. Describe your process. Share your techniques. And give others solid critiques.
Involve yourself in the community, show you are invested in being here, and others are more likely to respond in turn. I think the axiom "give and ye shall recieve" is applicable.
There are a couple more factors at play. Hopefully others will chime in here with more info.
I hope this helps!
