I'm new

I'm not an expert at any of this.  I'm not sure how all this works, and I don't even know if people read these things either.
Well, so the actually deviantart thing is not hard, but with photography and my drawings....well, i'm open for criticism, i just want to learn.

and also, i am not sure how to make the pictures less grainy...and if it's because the picture is too big, i have already tried to make them smaller...but it didn't seem to work...sooo yeah, help would def. be appreciated. well, thanks!
