I don't know if you saw that but that's what I found about this packet (it's on github). I think, merged with what you found about the "bits packing" we should have the answer:

<pre class="_prettyXprint">
struct C2S_CS_CREATE_CHARACTER (various size)
{
struct PacketHeader header;
DWORD lod0size;
byte[lod0size] lod0;
DWORD lod1size;
byte[lod1size] lod1;
DWORD lod2size;
byte[lod2size] lod2;
DWORD lod3size;
byte[lod3size] lod3;
DWORD charNameNumChars;
BYTE[charNameNumChars*2] characterName;
DWORD classID;
DWORD fixedSkill1ID;//Hack/slash/shoot
DWORD fixedSkill2ID;//Hack/slash/shoot
DWORD fixedSkill3ID;//Hack/slash/shoot
DWORD customSkill1ID;//choosen by player
DWORD customSkill2ID;//choosen by player
DWORD unknwownDword;//=41 it changes when the character has a shield (=43)
};

Note: Lod0 Lod1 Lod2 Lod3 are byte arrays containing appearance information.
WARNING: I am not 100% sure of their layout, so it has to be verified.
