#1 and #2 impressive designs, but stray too far from the logo attached. would like to keep the same look but want to see the O's revised with something different. remember the our plates will be an important part to our brand. feel free to use the current logo design and mix and match the O's utilizing a different style plate and colors.
#5 like this one better than #6 still need to see some variations of the plate. would also like different color combinations and tweaking of "sushi diner" font style and color. would like to see diner in a font that looks like a neon sign if possible.
#15 this is too detailed. would never be able to make this into an electric sign. great work, but to much intricate detail. try changing the plates colors and various stacked looks. continue to vary the colors. Also try using the plates in between Roll On instead of using them as the O's. Do not like the look of sushi diner but like what you are trying to do. keep diner level but use a different color. you also have sushi diner misspelled :)
