I have just a couple advices:
I personally like more the new logo than the old one, but I also think that the foot print must show up more... IT NEEDS MORE CONTRAST!!!
I think this can be solved by a little color correction:
as you can see in distrowatch homepage, when the logo is used on a non dark background it looses its strength.
A thicker red outline (maybe the red should also be a little bit lighter) and a nice "vibrant" foot print (it MUST shine more than the rest of the logo!!!) would strengthen it enough to cope with light backgrounds
keep up the good work, SL is great!
