ALMA

I think this mark is strong in general, I just might be concerned how you would make a sign from it. If you want to do raised letters the hears would be very tricky, as well as the thin lines from the hand. The colors are good but might now show up well for printing since they are light, you may need to do some testing to make sure they show well. Overall a good logo, but you need to think about how the logo will be reproduced in physical formats and design accordingly. Also, the logo will not reduce in size well, since there is a lot of detail. Something else to think about. Otherwise the design is quite good in general, well done!
