Roktiv the quality of your jpg's is what he is talking about try making them better quality or a diff extention like .png and it should fix your text problem, unless you just have a crappy editor, and if I wrong sorry.
Sometimes it is difficult to accept a 'hit' from the first try. Being in the Media biz, I love this one. I will be posting some contests next few days. Hope you'll submit some designs.
Roktiv, try switching on 'anti alias' on the text at the bottom, if you are using Photoshop highlight the text and on the bar at the top change 'none' to 'smooth'. If you are using a different editor, there will be a way to do it aswell. The actual quality of your symbol does look a bit choppy too, did you cut it out from somewhere?
