DailyUI 001: Sign Up

Well, I'm joining the fun. Here's to Day 001 of the DailyUI challenge! Be sure to check out the full pixel attachment, which has slightly exaggerated padding.

Question:

What size do you create your work at that translates well to a Dribbble shot? For this one initially made my image 1600x1200 (double the size of the Dribbble retina size) but then when I exported and scaled down, the quality was terrible. So resized the PSD design to be 800x600.

What do you do!?
