Thank you very much for your work - it is very nice. I do like #47, I do prefer #47 over #49 because it has simple font. I am putting you in top 5 to give you a chance to elaborate a bit this design. What about removing the shadow and for e.g. and maybe some play with the colors. This is only my suggestions but decision is yours - you know much more about logo design then I do. So I would prefer to follow your recommendations.
Hi Derek thank you for the opportunity. Actually it's not a shadow, it's more about 'layer' as you mentioned in the brief, here some updates #75 #76 #77 for you
