Really great replica build. The only criticism I have is the areas of the hull which aren't flat or simple angles appear rough and uneven. You should take a second pass over these areas as they can be improved by just tweaking the edges a little. look at each layer individually and count the steps along the way. If you have it going 3,1,3,0,2,3,2 you can smooth it out by going 2,2,2,2,2,2,2 instead. try to have the edge of each layer follow a pattern of steps such as 1,1,1 or 2,2,2 or when those don't work keep the odd steps evenly spaced like 1,1,2,1,1,2 or 2,2,3,2,2,3. if you do something like 1,1,2,3,2 you end up with something which look rough and bumpy unless you're trying to build a curve which you aren't in this case. Slabs can also be good for doing edges like these but wedges/heptas/tetras work well as long as you get the steps evenly spaced.
