# 24 looking good. I still deciding between few logos. To be honest at this point I don't know what is missing. I just feel something is missing but I don't know what. 24 is so far one of my favorite. If you want to explore more that would be great. I looking for something, don't know what exactly ;)
# 60 is good, try to make the outline thinner in the back like # 24 and the end little less sharp, if you look at design audi R 8 that doesn't have wing in back, something like that. (check work from blackstar)
