Shadow and Tikal

Pretty sure I spelled 'Ultiment' wrong
Okay... So on the Sonadow drawing I posted(WHICH TOOK FOREVER), People rated it badly and didn't give a reason! D:
Please, if you rate something, give a reason. And some intelligent guy posted a two word comment on my Silvamy picture I just posted.
I chose not to repeat it because it would make me sound like a moron.
So, on all of my works, please rate and give a reason for the rating if it's bad. I want to improve!! >:U
Oh, and I forgot not to draw pants on Shadow, Sam. Sorry 'bout that
Please join the Shadikal Club!
