Here's another Christmas scene, of a closeup of a decorated Christmas tree, with fireplace and sleeping cat in the background. Use freely anyway you like.
To make the tree, I collected various photos of pine tree branches off the web, used the background eraser tool to create a transparent image, then bunched the branches together to make the tree.
I created the round glass decorations from Photoshop, tried to put a reflection into the ornaments with a bit of shine. I also created the silvery tinsel icicles using Photoshop; the effect is so-so. (UPDATE: I improved the realism of the icicles using filters to "crinkle" them - now they more closely resemble the tinfoil ones you buy in stores.) Trees without a bit of tinsel always seemed somewhat bare to me.
Then I hung a couple of candy canes and an angel (all from the web) onto the branches, and added some lights (also from the web). I put a little background glow behind the lights.
Finally, a fireplace and a sleeping cat to finish it off.
I do Photoshops for the fun of it, but also to continually learn new techniques. And now I am somewhat less bored than when I started.
