This is my original design for a very heavy transport/frieghter/tug. It is from the early days of the federation and was used to deliver and set up collapsible deep space stations like the K-7. Not only could the Kraken ,and her two sister ships of the Goliath class, set up and supply a new station it could do the same for a starbase or a colony. The class had been used for many additional missions due to it ability to carry up to six different cargo pods.
I'm no CG artist that's for sure but I have these images of the class.
Well done! That isn't the final version but it is pretty close. The container pylons should be much shorter. See the top and side view. The hull and warp nacelle placements are correct.
