Okay - top 5. Nice work. Here are the notes for the next couple of days.
1. The fish look great. Top 2 fish don't need revision on the fish unless you want to. 3, 4, and 5 fish will need work to win.
2. Del Sol is two words. We normally do all capital letters with the D and the S being larger than the rest to differentiate the two words. In the logo, i want Del Sol Industrial Services Inc. spelled out fully.
3. The fish are cool, skeletal, etc. I would like the lettering to be just as cool, tribal, or skeletal but still easy to read.
4. I like the #84 entry with the round inclusive logo. It reminds me of a branded logo like the starbucks symbol. I would like to see a concept from you like this. I can see this on our give away coffee cups, shorts, etc. This logo could help build a brand...based on this visual image.
5. keep up the good work. feel free to play with some things outside of this box too.
