This is the first icon where I worked very hard to make it visible to all sizes. The original icon for this program, a must for any photographer who uses Linux, is poorly integrated with the GNOME desktop. It was created with Inkscape, the sources can be found inside the store. The dimensions are: 16x16 24x24 32x32 36x36 48x48 128x128 256x256
Thanks to DanRabbit for help me to develop this icon!
A couple suggestions are:
1. For the 256px icon try a thinner stroke and see if you can't add a little more detail. Perhaps a little gloss on the polaroid?
2. Watch your shadows. It looks like your shadow is gone for the 32px icon. But elementary icons have shadows all the way down to 24px
3. Make sure everything is aligned to the grid. It might just be the preview, but it looks like the alignment is just a little bit off.
Overall, these are tiny details, very nice
