Thank you so much for making this Stamp, it is just straight to the point! It's sad when you see a really wonderful piece, but the Artist that made it brakes in your face the "Comment before you fav please!!!!" Not only that some of us might not have the time as mentioned above in some comments but also sometimes you just don't have the proper words right there; so instead of commenting a "Awesome!" you preffer to wait for a better time when you have the inspiration for a more thoughtful comment
people SHOULD take this in consideration. A Fav really is a compliment, it shows you liked someone's work, appreciate it, and also support it by displaying it in your Faves, for even more people to discover it.
And the fact that some demand Critique, well, for all I know, when you know people would have something to Critique on what you did then this means you are already aware of what you did wrong without one or more people telling you that; the best Critique is the one you self-provide and your determination to improve.
So in the ending... thank you once again!
