right on Patrick!
sapelgas - You are getting better man. If you want to blur your backgrounds you should check the tutorial I made for selecting just the rider and bike(click the link in my signature to see my topics, two of them are the tutorials), that will help a lot to get the blur looks better. Also make you sure have anti aliasing turned to the max when taking screen (it can be done in your graphic card settings, depending on the card you use....or with some enhancement soft), that way you will get rid of those jaggy lines and the pictures will look a lot cleaner
gaetan - love the second, only thing I would change is that you should erase part of the rear tire so it looks like its actually in the dirt, the way you have it now it looks like its sliding on the top of it
and thanks a lot guys!
