Going unnoticed on these forums is something you get accustomed to almost immediately. I haven't been participating at IFX for very long, but generally the group here offers a lot of valuable advice and appreciation.
All of us could easily find advice on how to improve our art at virtually any art site but sometimes it's the words of strangers that sink in and force us in a good way to reevaluate our approach and feel positive about what we have and where we want to go.
Cue the contemplative music at the end of House M.D. right now as you imagine various artists mulling over their methods.
A favorite would be John Mayer's "Gravity".
Most of the artists here are supportive without sugar coating the advice, something I applaud.
We're all busy and deal with hectic lives so I hear what you're saying when sometimes all it takes is just a kind reply or a few supportive words to provide a bit of an uplift.
Nice portfolio man, keep it up!
