phew! For a second there, I thought that you took apart your venator to make this ship. After I saw it in the background, I put my attionion on the ship itself. The only major flaw that I saw was the color scheme...I am not a fan of the blue and yellow color scheme. Overall though a good ship.
P.S. NEVER take apart the venator, it is one of the coolest mocs on mocpages!
It looks more like a LEGO classic space ship than a Star Wars ship, to me. It's still every bit as cool, though, and perhaps cooler: there are less classic space MOCs than Star Wars MOCs, making this ship more unique, and therefore cooler. You should try more work with this style, I really like this.
I know it may not look like a "Republic ship" due to the colour code, but i think its a great MOC :D there are so many great features to this ship, especially the large window facing the workroom to see the container. I thought that was very thoughtful :) The greeble, pipes and hoses, booster engines look great and the sheer size and ability to stand is those exact criteria which echoes the brilliance of all starwars ships :)
