looks nice, the present looks like its made out of clay making it a bit more square might help (decimate modifier might do the trick), the ribbon looks ok but you may want to model a loop/knot where the strings meet or not have ribbon at all. The scene does look a bit bland though, have a look at maybe putting in some trees in the background or an overcast sky could be nice.
the scene also looks very bright, you can’t really tell whether the background is seperate from the foreground. maybe try adding seperate spot lamps (you could even put lights on the north pole sign). maybe a dark blue hemi with low energy and some very light orange/yellow lights on the sign?
also for compositing add depth of field and make the present in focus as it is important. don’t go too overboard with the blur though allow the viewer to still see the north pole sign.
if you wanted to you could look into sculpting the snow to give a sense of scale.
