I have spoken to some of the others in my company, and we would like to see some possible alterations: 1) have a little more of the bull's face showing, maybe just enough so one eye is visible. 2) Can you try putting the design in a shield/crest shape instead of a square?
Both of these we just want to see what they look like, we may still end up liking your current design the best.
Also, could we see the lettering slightly larger in proportion to the picture? As it is now its a little hard to read.
the one with a shield, one thing i would like to clarify you, i designed the icon with half-part of the bull's head from the rear top view, so adding eyes looked a bit odd to me, also guess it does not fit with the shield type, just posted this entry to give you a look as you said it...are you interested in using orange as a color in the logo???
