Most excellent Sniperdude! I love the oily greasey look you have got to all the tools and timber... just like a real maintenance work area. The engines stored on oily wooden blocks is a nice touch as is all the little details you have added.
You seem to prefer overhead photographs .. but this leads me to my 2 little nit-picks that you might want to keep in mind for again. Looking down onto the timber flooring, all the planks are very wide for this scale. Although quite possible ...... how normal would this be? Bigger trees that wide timber like this would come from, would be a bit more exclusive than to be used as flooring for a garage floor. Also it is layed a little too perfect. All planks are perfectly uniform in length. This all sounds a little nit.picky...... whereas in fact Im really admiring the fine finish you have made on the timber.
The second is... the emphasis again is from an aerial view. But looking at it from ground level there is no background. A wall or bordering area would have added to the scene, and made logical sense as the table and engines would have left tight to it rather than sitting out in the open floor.
Sorry to sound harsh .... thats not my meaning. Just the things i saw when i looked at the dio! Otherwise i think it is excellent. Nice one!!
