#12 - Very edgy, like it a lot. Can you bring the left side line of the "C" "up" so the long part of the right side of the "V" becomes the "C" instead. Right now it reads a little like "SVT" not "SVC." Give it a go and thanks. #13 - Interesting. I like it. Can you try a different font? This one is a little too plain. Thanks!
#25 is great. Don't know if client will go for it, but it is really a good take on this logo. Thank you. #13,27,30,and 26 won't work for this application. Wish I could give you some definite reason, they just don;t quite work. #29 is very interesting, thank you and #38 is good as well. Will pass both these to the client
