I like where you're going with this one. Maybe instead of the "7" dotting the "l" it can be to the side of the wording, or it's own element? I'd also like to see some use of the "SIG" acronym if possible.
Thanks for your valuable feedback. I tweaked it to make it part of the wording wich is very interesting. Also uploaded another color scheme. I will think in the SIG acronym, though I think sevenimage is a very nice name by itself.
