Wow! Another cool entry.
I really like your “worm” it reminds me to those abyssal (i don’t know if it’s the word) animals. (the ones wich are at the deepests oceans). The model looks really well, lot’s of detail in there. Are you modeling the high poly one first?? And as they have said earlier it seems to be designed for normal mapping. 
Really cool one 




I’ll do something with that…
