I like this design is elegant and has presence. I have two comments. Firstly there is a similarity to the famous Ferrari horse logo so I am sceptical about it. Secondly can it be fitted in a sheld type also, I am thinking when it is printed on t shirts
I created some new concepts and I hope you will appreciate them. Also don't worry about the Ferrari horse, my logo represents a completely different horse (mythological horse) and is unique and distinctive. I think this logo will looks well on prints and t-shirts. Let me know if you have in mind other changes.
