Overall great work! You have definitely captured the essence of the brand. I like the calming and professionalism of the color scheme but would like to see some passion colors inserted like in #2 throughout your themes.
#3 - I like the layout with "Dyer Sales" on the top row and "Strategy" on the bottom. The one element that I would change is the figure reaching for the star. This reminds me too much of "Make A Wish". I would love to see this concept with a different figure.
#1 - I like the layout with "Dyer Sales" on the top row and "Strategy" on the bottom. I do not tend to like the blue and gray color scheme and the figure reminds me of a flower.
#2 - I like the color scheme and what you have done with the 'y' in Dyer. I like the layout with "Dyer Sales" on the top row and "Strategy" on the bottom. I would like to see the a different figure and the star removed but like the swooping motion of the 'y'.
#4 - See my comments for #3. If there is going to be a figure I would like it to be in the "Dyer" part of the company name. I would like the layout to be two levels like #3.
#5 - This is a bit two simplistic and the gray and blue color scheme is a bit muted for me. I like the idea of an outlined word like you have done with "Sales".
