We like 55 but would like to see what it looks like with just 4 or 5 coloured letters and the rest black. Also be good to see what it looks like with 'element' in capitals.
We actually like all your designs but would like to see some two-tone designs.
We also like 36 but the E doesn't look like an E and people may just read the word 'Lement'. Can you may the E clearer. Also can you try this with a finer font more like in 55.
And....finally can you produce a new design that has an abstract pattern that flows through the word 'element'.
