I wish I could've selected more than one option! I've been preparing to convert my dA into a technical blog and not-so-serious online portfolio, but I also appreciate and welcome any advice I can get. Plus, I also like to share what I make with other people. I think it's fun.
In addition to sharing what I create, I do like to garner feedback from my Readers... not merely because I'm am attention whore but also to hone my technique and skills and improve. But getting those reviews... there's nothing like that in the world!
