I finished these about a week ago. But then my router decided to pack in. >:/ And I had to wait for a replacement. So, I'm rather late to the party, sorry about that, but I still wanted to contribute.
Mostly reiterating what nanxaimer has already said. Also probably not entirely 100% accurate but hopefully still useful/helpful.
Here is a profile of his head, featuring my best rendition of that little clasper thing that sports his bow. As you can see it has a gem set into a part of it that curves up. This shares the same colour and glossiness of his bow tie (not shown here). In addition, the pieces that make up his neck have this shape when viewed in profile, the same shape as those sweet/candy necklaces.
The hole in his carapace from which his neck protrudes is shaped roughly like a whalebone. Above it is a small break in his dark purple armour which is a lighter purple and is striped, dark purple (outer) and yellow (inner). And his shoulder pad has a dent in it, allowing him to raise his arms upwards, as it does not move that much.
And lastly his hands/wrists/arms.
He has very long fingers. Normally fingers are the same length as the palm, but his are twice that (arrows in grey). And as fingers are wont to do, bend in two places, if we ignore the bend at the knuckles (arrows in red).
The part on which his hand is mounted is a creamy colour and striped in either orange (used here) or a shade of yellow (not the vibrant yellow of his stripes), it's hard to tell which (this is an edit correcting it from pink). It is also slanted at the joint which connects it to his arm. The stripes follow in the same direction as the stripes on his arm.
Leading me onto: the stripes on his arm. He has three stripes in lighter shade of purple on his upper arm and three more slashed with yellow on his lower arm. I find a good way to remember their direction is down and out. That is, down his arm and outwards (although perhaps not quite as dramatically as I've done them here).
And that ends my contribution as Nanxaimer has sufficiently covered everything else and I literally have nothing to add.
Again sorry this is soo late but I hope this was at least somewhat useful.
