Ooo yum! I think you need to rotate it a bit to make it straight. Draw a line between the two points of the rim to see whether it is straight or not. It tips to the right now.
Not quite sure I consider this an "EXTREME close up". I do think the shot it ok though. Focus and clarity seem good, and lighting is alright as well. The background to the upper right of the cup seems to have something strange going on with it, and I wish the lines were lined up with the photo. ~Heather~
