Yes Wales won and we're set up for a possible slam again in this years 6 Nations. Personally I think that Ireland are the team to beat this year.
At least we beat the English!!
Rendering is basically photography. You arrange the items and see what you get. You render again and repeat (where have I heard that before!). It's more like directing than original art - you have the objects to work with and you make the best of them. If you model (3d objects I mean) then you can do what you want. The most time is spent fixing something you forgot.
Masters such as Restiff and Scavenger use their expertise with 2d image packages to change the final image into something better but I'm to lazy or inexperienced to do that.
