I guess I put about an hour to an hour and half on each image. But I was watching a hockey game at the same time, so... I had to dig pretty deep into the FedEx website before I found logos I could use also. I think that took more time than manipulating the images!
I am learning to use Photoshop 7 right now, but I am very familiar with Paint Shop Pro (poor man's photoshop). I kind of bounce between the two programs right now until I figure out how to do everything in Photoshop that I can do in PSP. I can tell that PS7 is waay more powerful than PSP, but the learning curve is holding me back.
And, yeah I did the UPS truck on HondaSUV.com's home page... it's here also under the 2005 Honda SUT thread.
