After talking to a few people and getting their opinions about my edit I decided to go back and re-edit the shots together before I proceded any further. I am quite satisfied with my re-edit and have locked this one in as the Final Cut.

This is a subsurface test I created in Houdini with a bit of help from an old professor's tutorials. With some minor tweaking and adaptations to it, it fits my vein man just fine.

Here is a rough comp of my middle shot. It is nearly finished with just a little tweaking here and there along with getting the composite right. I think that once I get this shot locked in and pretty much finished the others should come pretty easily since they follow the same place. Hopefully everything falls into place.
