Pencil sketches within...

A lot of people around here already know what i do everyday, but what i haven't mentioned yet is that I like to think of myself as a writer as well (on the side)

...............I'm a writer (on the side)

Anyway, now that that's outta the way, I just finished a two year project that can be described as (to coin a term I picked up from someone here) a space opera.
The book also has a technical manual as a forward to get the reader oriented to the status quo/technological level/social level/setting of the novel.

I've done some partial pencil sketches of the primary ship in the novel and was hoping to get some feedback.
