Basic buttions Seeking feedback

Just looking for feedback. I recently decided to switch roles from programing to art. I'm still a art newby but I'm hoping to be good someday. These are genric buttions I been working on. I used MS Paint and paint.net. I love MS Paint for the ability to easly make my outlined image and shape. Then I use paint.net to bring it all home.

Added some simple text to a few so others can see how nice they might look in a game. What do you think? I been dabling with art for about a month.
