THANKS to everyone's feedback. I really appreciate all your suggestions. I live in Boston area and will go to try few coffee houses people recommend in the weekend. Hopefully I will be able to find someone showing me the proper frothed milk as well as pouring.
I cannot agree more on the comment about the milk consistency. I also believe it's the most important part, and this is the most mysterious part to me. I am able to find the right position for my steam wand to stretch and create sheeny milk with microfoam. However, I just cannot figure out what the proper thickness/density of micro-foam milk should be. This is the hardest part to identify from all the videos. Same thing, I have hard time to understand how liquid the milk should be. Can anyone possibly use words to describe it? (sorry...I know it's hard, but I am not sure if I will be lucky enough to find someone to show me in person)
Thanks to Randy and David for the tips. I will try them tonight, and maybe post few pictures of the results as Chad suggested.
FYI - From all articles and videos that I read/watched, I decomposed the process as follows and also included different ways people used to implement each element. (the process I described below stops right after starting to shake the pitcher)
Creating micro-foam milk - Michael is right. It slightly varies by different machines. Again, it's hard to tell how thick/dense the frothed milk should be from the videos...
A. Height to start pouring1. spout right on the cup (pitcher almost touches the cup rim)
2. 3" - 5" high from the surface of espresso
3. Higher than 5" from the surface of espresso
B. Stream (flow) of milk to infuse into the cup at the beginning (rough measured by eyeball)1. Thin ~1/8" wide
2. Moderate ~1/4" wide
3. Large ~1/2" wide
C. After starting to pour, movement before starting to shake pitcher / the "white" appears1. Keep steady without moving until the "white" appears
2. Circle the milk stream around the center of the cup
3. Keep moving the pitcher up and down
D. Timing to start shaking the pitcher1. When the cup is 1/2 - 2/3 full (but no "white" appears on the surface)
2. When the "white" appears on the surface
E. Timing for the milk (white) appears on the surface1. After starting to shake the pitcher
2. It just appears automatically (just pouring without shaking the pitcher)
F. Height of pitcher (spout) when creating the art (rough measured by eyeball)1. About 1" high from the surface of coffee
2. About 2" - 3" high from the surface of coffee
Anyway, this is what I observed. Any comment? Obviously I have not found the right combination yet. If I miss anything, please let me know.
Can any one please explain the rationale of the latte art? The only explanation I found so far is this:

Thanks again, everyone.
