The poster on the right is a tad out of perspective.

Please post source links.
Edges need a lot of work...instead of using the magic wand, use the pen tool or lasso tool to extract objects cleanly.

I agree with CMYK here

I was trying to add the steps and source links when commented. I could probably have spent a little time on the edges. Lasso tool is probably the best idea. Worked this out during lunch. Thanks for the comment.

The truck and girl are not published photos...no url. They are from my own camera and taken by me.

Sorry that I used a copyrighted image...the windows. They really weren't that important to the image and I really did think I had borrowed it from an open source. I fixed the windows by taking them out and using the original windows of the truck photo. Probably looks better anyway. The truck and the girl come from two of my own photos. They are not published on a web page and don't have a url. I have displayed them in my step by step. Sorry that broke the rules on this one, but it was unintentional. I really just enjoy trying to come up with the image. Hope this works now.

Let's try this again. I have fixed the step-by-step and taken out the truck that i used for the windows earlier. Hope that corrects the issues. I'll be more careful next time I enter a photoshop contest. Wish i had more time to get involved in these things. Sorry for the troubles.

Using the BURN brush on the squashes left undersides to match the shading on the tomatoes will make it look more realistic (fantastic Idea) IMHO

Its a lot of work but id liked it better if u had replace all of the tomatoes on the stem with these squash, the squash look a little overexposed imo other wise the quality is good.

thanks! Drivenslush & Eladine........
