I'm gonna make some but hopefully I can convert them from OBJ to DTS
EDIT: Pencil completed

Non-wireframe

EDIT 2: Found a DTS exporter :)
Im going to give you one thing that very few people on the forums will give you without needless insults thrown in, This model has to many faces try and limit your cylinders to 8 sides unless you need more then do NOT go above 16, you should have left the black lines out of it because they are un-needed detail details that just raise the poly count, also maybe not have the tip of it come to such a point and go for a more blunt look, The colors are good accept i think the pencil lead should be a darker shade although that is just my personal preference, im not saying this to be a richard and stop on your models its just what i wish someone would have told me before i started modeling, Best of luck to you and I wanna see some high quality add-ons out there now.
