>Is that any good for making models with a low ploy count and file size?
sure, it's good for everything. I use it for my game's models which are sort of low poly. They don't look too good since I'm a new noob but Bleder sure is more than enough for low poly stuff.

some goblin I made for a game I'm working on. I'm quite new to 3d stuff, so decided to go with segmented limbs so I don't have to deal with deformations.
