Bitwyre lock illustration

This lock illustration was made for Bitwyre, a cryptocurrency exchange. I feature it on their landing page in the security section.
My process was to generate a fractal texture and apply it over a vector drawing. I used the same texture for all of Bitwyre’s illustrations.
One thing I usually wonder about when seeing someone else’s illustration work is how they came up with the optimal illustration style and if it was the only one they tried. I did my fair bit of experimentation on this project and you can now also take a look at this same lock illustration made in one of the other styles I tried. I liked it a lot and would be happy to use this style for some other project. In the case of Bitwyre, however, we were after a more solid look with the use of the texture. The colours changed as well, in accordance with the rest of Bitwyre’s branding.

Could you imagine Bitwyre landing page using the alternative illustration style and colour palette? Do you think I made the right decision using the blue lock and discarding the purple one?
