Engineering decals are on, I must admit I've found the JT Graphics window decals to be rubbish - they break apart easily and the backing isn't quite transparent enough to blend with the hull.
I'm glad I got a second complete set, as I had a lot of trouble with the draft markers print falling apart too and general decal bending and misalignment. The whole kit is slightly out of alignment however, which does help hide some flaws.
