My first blender render - A Die

Hi i am new to blender (only been working on it for about a month) my friend, Spicy (Who is also on this forum and is a newbie, we help each other), has taught me all the things i know on how to get started. My first render is a dice, its not finished yet, i have had some problems like i made the actual dots on the dice too big and they show up as bumps in the adjacent dots (you could notice this if you look hard at the face with the 6 dots). i have had trouble with the render as it is not the best quality, because i am working from a laptop and so cannot set the render level to six because it freezes my laptop.
