Tyranid Eggs Terrain

I got another piece of terrain done. I found in the flea market a Mega Bloks Dragons egg and transformed it into a Tyranid egg.

I removed the matte foil and cut the shield in the front with a hot cutter. I glued the egg to a cardboard along with some air-soft balls. I bought some paper balls from the hobby store and the larger eggs are ping-pong balls.
I poured PVA glue over everything then super glue to get the nice irregular shapes.
After all the glue dried I sprayed the base with black paint.

 I did a heavy dry brush of  a mixture of brown and yellow, then dry brush with pink and another dry brush with white. Some of the eggs I washed with blue.
