From the pics my first thought is pic no. 2 - no, no, no... it's a bass, not a baseball bat! LOL
Pic no. 1 - yeah, from the pic it looks like you've got quite an angle going there - and my first thought is for you to bring your elbow out a bit from your side.
But pictures are deceptive. I have some other questions and possible answers:
1. What else do you do that might be causing your wrists pain? Do you play computer games that are wrist-intensive (First-person shooters et al.)
2. Do you work on a computer a lot? Doing graphics/photoshop/Flash/Illustrator?
These sort of activities take an awful toll on your wrists - both of them. If the computer is a factor, you may want to investigate some ergonomic equipment - mouse - keyboard and possibly some wrist wraps like these:

And finally, here are some bass player stretches for you:
1. Stretch fingers back opposite of the joint. 10-15 seconds each hand.
2. Bend hand forward as far as possible stretching wrist for 10-15 seconds each hand.
3. With hands and fingers extended in front of you, slowly rotate each hand as far left and right as possible 10 times.
4. Starting in same position, rotate hands in circular motion through full range of motion.
5. Drop hands to side and shake out.
6. Pull elbow with opposite hand across body. 10-15 seconds each arm.
7. Clasp hands and extend palms above head.
8. Find muscle that controls arm movement above chest and under collarbone. Massage and warm up muscle.
9. Find forearm muscle that controls finger movement. Massage and warm up muscle.
Take care of those wrists! You need 'em!
