Ok so here's the Canon PowerShot A660. I'm trying to photoshop an A640 to look like an A660. I made the lens larger, eliminated the on-board flash, added a hot shoe, but it still looks like it's obviously photoshopped/gimped/etc.

I still don't have the Canon logo modded properly, and the megapixel count is partially obscured by the large lens. It would use an APS-C sensor (and since it's a Canon it'd most likely be a 1.6x crop which would make the lens a 24-96mm equivalent. Megapixel count would be probably 6 or 7. 8 might be a bit much.
Also the lens' physical aperture is still too small. (IMO when wide open it should be closer to 50% or more of the lens's outer diameter.) As for the max focal length, I know that is possible in that size (or similar size) body because of the SX100 / SX110. What might be difficult is the relatively large maximum aperture, but since the lens takes up the entire vertical height of the body, rather than only approximately 55% or so of the body's height, it could probably have a larger maximum than the F/4.1 on the A640 or the F/4.3 on the SX100/SX110. (I wanted to make it F/1.0 at wideangle, but then that'd probably make the camera cost at least 90% of the Rebel XS body's price.) Depth of the body would be the same as the A640 or SX100/SX110, but height might be a few mm taller.

The flash hotshoe is probably not to scale - i just copied it from a G9 without regard to scaling, but it looked close to accurate. (It's there because of the fact this camera has no on-board flash (to make room for an extra large lens.)) Also you may have noticed the camera doesn't have IS. Hopefully the larger sensor and faster lens might partially make up for it. Maybe it still needs it, though, due to the lack of an on-board flash. (Maximum ISO would probably be 25,600 (with maybe a 51,200 1.5mp scene mode option). Pixel density of a 6mp APS-C sensor is between a 12mp FF (Nikon D3/D700) and a 21mp FF (Canon 5D Mark II) sensor.)

Here's the XCF with layers and stuff. (http://www.box.net/shared/mmif62qmbx). The original pic was from dpreview's A640 review.

So what techniques do I need to use for making it look more realistic? (GIMP's freehand select tool was acting up a little today so I couldn't always see the selection so I had to guess. Also I can't seem to figure out how to combine different select tools like it seems like you can in photoshop.)

Or, should I "mod" this SX120 instead? I've made much less progress - some of the lens text is still wrong, and I haven't added the hotshoe yet. It too would have a 6mp sensor, but would be full frame, so the focal length printed on the lens would be the 35mm equiv. (and actual) focal length.

Or, would modding the G1 Mark II, G9 Mark II, C-3040 Mark II, LX3 Mark II, or DP2 Mark II be better?

(Note that I haven't pic'd the G9 MkII or the DP2 MkII, as GIMP seems to have (temporarily, hopefully) stopped responding... hopefully it'll come back to life before too long...)

In case you haven't noticed a trend.... IMO I think camera lenses in compact cameras are much too small relative to the size of the body. Cameras like the SX110 or DP2 are a huge improvement over some of the older cameras from like 6-8 years ago, though.
