Hi - I particularly like design #21. Some of my earlier sketches were along similar lines (but not as good, of course!). The style of tree is great and I like that the word 'sensing systems' is similar in size to 'environmental'. The pictorial design captures the environmental part of the business very well, but I need to also incorporate the technology aspect. Do you have any thoughts on how #21 could be modified to give a sense of harmony between the environmental and technological aspects of the business? Regards, Darius.
