I believe you were the one who said that what you consider good art is art that impacts you. I agree with you and hence picked the jawbone one because, really, what matters is that what you create impacts people, not what you made it with, right?
If I were to not deliberately miss the point, I would tell you to keep at SAI if it's a challenge you enjoy. If you feel you're not quite up to scratch then keep at it until you get to a piece that satisfies you. And until then, like you always have, continue to post your works with the courage it takes to face a hundred angry rams and know that no matter what you post now, you will always post a better, improved work later, and you can only ever improve hereonout.
But that's too many words for a valid option, so jawbone it is!
hm... a lot of people im watching who seem have a lot of watchers all seem to ask these types of questions to us eventually (what do you people think of this new thing im doing? ect) ... but the result always ends up being something along the lines of "do whatever you want to, oh great one! we will support you in whatever path you choose! be it hail, rain, or melted snow!!!'' WE WILL FOLLOW YOU, MASTER!
so i don't think it matters i mean, your gallery is pretty random anyways... d: im guessing just as long as you remain laughable, you'll be all right.
besides, i tried flash and it was way too complicated for me. you and your vectors! oh you artist you! i think if you figure it out after a bit you'll do totally fantastic
