Entry # 4 - I like the concept of doing something with those "O"s. Not sure I like the blue colour so much but I do like grey in the logo in this example.
Entry #1 - interesting idea but that owl look would need to be polished more and the "understood" below is almost getting lost. The font doesn't work for me either.
I would like to see a concept of an owl sketch on its own with the name of the business for comparison. Also the colours - something we can worry about later. I know I might have suggested blue, brown, grey in my profile but I am open to any creative ideas. Thank you for the current efforts! I will ranking/commenting every day.
