I tried to draw today, and this is what I produced, I like it, not quite sure what it is supposed to be. But here it is.




Any comments, suggestions...?

Also, do you think I could be good enough to open up my own art shop?

It's cute! You should draw avatars of friends or someone who has an inspiring look to get a hang of it. That way you improve, you get used to your own style, you will have more confidence in yourself and you will understand how long it takes you to complete work so you can give people a time frame for when you do open shop.
Experimenting with different media is fun also. ^^

I like the expression of the face, the attire reminds me a lot of Morrowind. (First picture)

Well, in the first picture, the left [our right] sleeve seems bigger than the other sleeve. Also, the hands are way too small, if you put up your hand to your face, it covers up a big amount, but that wouldn't be the case in that picture. Also, the bust seems too big for the head and body overall. Also, the head seems a bit deformed but other than that it's good ^^

The first one looks interesting... It looks like a jugular preformer of some sort... The seconded one looks like some sort of worm? o_o I like it, though. xD Very creative. xD

both of them look very nice!
I really like your linework it has alot of energy. One thing you can try to do is ink the lines and make them alot cleaner and it will really bring your stuff to life.
The second drawing is really interesting. I'm not sure what it is myself, but sometimes with art you don't have to really understand it to aprieciate it. ^^

Personally, I don't want you to clean up the lines. I like my art raw. ^^
In that same way, I enjoy the twisted look the figure has. Style trumps anatomy sometimes.

That second work is rad.

I'd love to see you go even further with these crazy shapes your finding, and even bolder with your line work. If that makes any sense.

The face looks a too distorted in the first one, and the chest is too big.

I would also suggest cleaning up the lines on the second one. I can barely tell what it is.
