I don't use tutorials. Edit: My bad, I didn't add a prefix. If a moderator could do that for me, it'd be nice. I'm looking for "CnC" obviously.
Looks like we have something in common, then. I never use tutorials. Great job on the first and second. The third and fourth are alright. You did a great job with the lighting in the second one.
I like the second one. it has good lighting, and the colors are blended really well. The other ones are okay.
