Wow, glad to see the finished product Valar, thank you very much! Excellent painting there I must say, I like it all very much: All the colors are fitting, the blendings looks about perfect, gems are awesome, contrasts are very well made all great stuff - Also, I am jealous.
You asked about the EMLs: The bone color is about perect I'd say, same as on the hull's fins - Personnally I'd do some sort of shading or inking in the actual launching tubes to give them some depth, and why not do some of the weapon's gems like you did on the Force Field generator fins (the gems on them looks great)?
Just saying, as from here the guns look a 'very little' bit bland compared to the overall look of the tank. IMHO
Keep it up dude,
Starky
