i noticed you were shooing at f/3.9 and ISO 400....

for macro photography, flip the dial over to Av mode (aperture priority).

then set your f/stop to around f/9 (large f# gives you more depth of field, smaller f# gives you less DOF but a sharper image). go into the custom functions, and turn "mirror lock up" to ON, and "long exposure noise reduction" to ON. also, be sure to use your remote timer.

you should be using a tripod when doing macro photography in aperture priority....thus you shouldn't really need the ISO.....so take that back down to 100.

try those settings out and see what kind of pics you can get.
