The Heartbrick Kid

I want to make a MOC of some sort of space truck/cargo space ship, mostly in grey (a combination of grey and dark) and touches of yellow and red. I already made this, but I want to upscale it a bit and I'm looking for a set to would make for a good base or parts selection. After reading some reviews, I was thinking about Creator 6753. Do you have any other ideas of sets with large amounts of grey/red/yellow tiles or smooth pieces?

Just when I thought I was out, they pull me back in... Hello there! I've been lurking for a bit (thanks to you, reviewers, who helped me decide what to buy) and I've decided that it's about time I start asking questions. I'm 25, I've been out of the Lego business for a long time but I got back in 2009 when I discovered the Indiana Jones sets. A few purchases here and there and then... nothing. At the time, I wanted to make a 1930s gangster brickfilm, hence the Indiana Jones sets but stopmotion is so time consuming that I had to let it go. Fastfoward, we are now in 2012 and out of nowhere, I decide to buy Grand Emporium and Fire Brigade. That's it, the rush is so pure, so perfect that I'm hooked again. I'm back in the game! Within decent limits of course. And already, I'm thinking about trying to set up a decent MOC but there's so much to learn before that, so many beautiful creations to study that it may take me some time to do it right. Anyway, I'm glad to be among you now!
