hey cerulean, looking good man i took your image and edited in 1 thing, i'm glad you took my idea of the glass surrounding the inner bit and it looks awesome!
notes:
about the fragile part the bomb looks too fragile to me, if it were dropped straight down it would buckle and break the glass. the digital timer bit im sure people have already stated they would love to see a timer on it and a digital timer would look perfect with this bomb, preferably on the front of it. i would imagine a rectangle shaped built in timer.
these are things you can try and see how it looks, scrap it if it doesn't work out.
