Experimenting?.. Very nice. I realy love it but wish you to add some typo to your stuff and work more on the background. Other than that is just great!
nice hughe's but i think a bit more shadows would make it more effective, try some perspective and foreground middleground by overlaying the objects maybe? btw dude did you get any good shots the other day? when you get some time off come up my way and we will go on a mission lol
