Need some help... Concept Photoshopper needed

[christhenoun]

Hey guys...

So I'm thinking of a new project. I'm stocked for the new codex, and really want a unit of Devestator Centurians. However, the models are FUGLY!

 

So I've come up with a concept, 'The Centurian Weapons Defense Platform'. 

 

I'm useless with any and all forms of technology, I just about manage with a laptop and mobile, so I require the help of you people... Surely someone out there is good with some sort of Photo manipulation software.

 

Would some one be able to out together a mock up concept image of what I want?

Basically its the Thunderfire Cannon's carriage. The Tracks and flat bed with the frame. In the middle of the frame is a sort of ammo hopper, this forms most of the body work. On one side of the hopper is perhaps a Landspeeder Typhoon's missile launcher (on its side) and on the other is a twin linked Las cannon. 

 

Are there any budding brothers able to help? 

If the project goes ahead, you'll get credit for the design process!
