Hasta La Motion!

Here is my first topic, and my first try to do something in Nuke. I’ve got a lil background in after effect though.
Here is my noobish problem :

Btw, if you have any recommendations, feel free to add it in your comment! I’m a total newbie, so It’ll be very appreciated

Cheer,
ek.
