Dear sir! Thanks for the feedback! The idea behind the design for entry #1 is as you serve both real estate and oil/gas industries -so i connect the S2 with dot.
The idea behind entry #2 & #3 is - as you see the negative space of white you see S2 in layer style which represent LAND - GAS -LAND - OIL ( hydrocarbons are broken down to oil and natural gas ).
Hi Sir! I have submitted some variations as you requested! I have also update the entry#3 into entry #72 .Hope you like it!Your feedback will help me to serve you my best.
