Hi rcbedg,
Thanks for your feedback. Here are some new combinations with random backgrounds for you:
#72 | Bolder and italic font, new color scheme.
#73 | Bolder and italic font, new color scheme.
#74 | Same font, one color logo.
#75 | Bolder font, same color scheme.
#76 | Italic font, one color logo.
#77 | Same font, one color logo.
I will prepare some variations of my concept including the underground mining theme, could you tell me which of these combinations is the best for you?
