I've skinned my character now and made some more changes to the rig. Turns out fat characters with clothes are really hard to skin.

As I told Nicholas in an e-mail, there are still a few issues:

• Knees/legs twist a lot. This seems to be because of the geometry? Not sure, don't know how to fix it. If you pull out the knees and pull his feet forward, they straighten out some.
• Arms/shirt - elbow area. No idea how to handle this - the shirt is RIGHT at the elbow bend. Right now the geometry penetrates.
• Clothes separate at some parts if you move the character too far.

I added curvy C-shaped spine controls - Nicholas agreed that the rings might be too cluttered, but I figured these would be easier to grab from more angles than the lollipop controls.

I've sent another draft to Nicholas that has the IK/FK switch included and a few more changes.

There are still a few issues I'm working on -

• Controls a bit ugly (IK/FK switch is just a circle above the elbows, FK controls for arms not placed very well).
• Need to add spine controls. In an earlier e-mail, I believe Nicholas requested rings. However, the torso of the character is getting a little messy, so I've asked him if he still would prefer rings or if lollipop controls would be acceptable. 
• Thumb controls still rotate weirdly, don't know why.

I obviously also need to skin the character. I have cut away and hidden some of his geometry, which should help the penetration issue that would have arisen otherwise.

I've got a draft of the rig that I've sent to Nicholas. Here are some screenshots showing the setup.

There are still several issues I have to work out, as I told Nicholas. They are:

• The hands have rotated strangely because of the elbow pole vector - I haven't been able to fix this yet 
• The thumb ring controls will not align the way the others have, I need to fix the orientations here or something
• I would like to add an IK/FK switch (the rig is currently only IK)
• Potentially add finger controls to select the whole finger (an easier way to do a finger curl)

Also, I have not yet skinned the character. I'll work on that after I've gotten the rig more finished.
