I'm dabbling with sketchup. Getting medium competent with it. A great FREE tool. But what I like most, vs doing the actual modeling, is importing useful things I don't want to model. Cars for instance. Also, the little standees, always facing the camera, are better than perspective for scale.
The bottom one is afterthought edits I'll never do to the original. Might drop them in on photoshop layers.
I've decide 50mm is probably the best all purpose lens.
