It would be nice to be able to afford someone with constructive criticism(s) when something is posted (publicly). However, "in this day and age," it seems like offense is so easily taken, and often the result of miscommunication, misunderstanding, and/or de-constructive criticism(s) (the critic is (borderline) offensive, whether intentionally so or not).
Personally, I have avoided uploading/sharing simply because I am unable to even hold a guitar/bass *properly* anymore, and with various physical shortcomings, it can be quite difficult to capture even one *good* take. Capturing inspiration as I could in the days before my accident are seemingly long gone. Thus, I keep it to myself. No pity parties, no, "aww, poor girl," no sympathies necessary. Just offering another side to things, as it is not always cut and dry when it comes to the "whys" of life.
If I were able bodied/minded and recording myself, I would want a (proper, helpful) critique, and not one from someone atop a mighty steed (oh Hail thee! Brave and noble Knight!), but rather from another guitarist.. another artist.. another person. Think.. "How and what would Guthrie Govan do to help this person?" rather than, "How would R. Lee Ermey handle this miscreant?" And to those on the receiving end, review, discuss, implement, rather than angry debate, vulgarities, and denial. It is art, and subjective. Listen to free-form Jazz (ugh, IMO
). Then listen to a band that is so precise and stiff that it sounds inhuman (ugh, again, IMO). Find your place in there. Explanations and practice, not excuses, ignorance, and laziness. IMO.
