Thanks for all the great tips, folks. I have started playing with lights settings. I couldn't quite understand if I should have the same settings for all the 3 default lights. I tried to make those same settings on all 3 lights, and it didn't seem to take. This is what I got as a result anyway. (I saved at the higher resolution and size, and as a tif. Then I went to PhotoShop, reduced the picture, and saved a copy as a jpg.)
