Sometimes I think those posts are what they call a "humble-brag"". While trying not to appear 'braggy' about your work, you mention a minuscule detail you can find wrong, so others will say, " Oh, no, it's so beautiful just the way it is!". But I think we can all tell when someone is actually having a problem figuring something out, and who is bragging. But, if you're proud of your work - just say so- we all have projects we would like others to admire!
