First, Sorry
I would say, that there is a lot that is wrong with Durango class and Oaxaca class drawing.
my short list for Oaxaca class:
http://shipbucket.com/drawings/420/file
- I don't see enough change from the original drawing, to justify you'r credit. I would call adding underwater hull not enough change to the drawing.
- After what I can find on the internett, the underwater hull is wrong.
my short list for class:
- color totally wrong
- underwater hull wrong
- shading is.... yeah not good
- shape of aft deck, helicopter deck, is wrong.
- missing hatches bellow helicopter deck
- funnel shape wrong
- ship and parts should have matching color.
I suggest you study all the picture you can find on the internett. if you can't find underwater hull pictures/drawings, then there is no need to speculate and draw an fantasy underwater hull
