Either one would be a good choice, but before you decide, and considering you have the freedom to play with them a little, there are a couple of things I feel might work to combine the two designs into a really nice logo.
1. cut the leaves from the second one and place them into the first one the shape of the three leaves could follow the capital C and add some more colour and flair to the logo.
2. in the first logo: change the colour of the "Auxano" to be the same colour as the word "Creative" in the second logo. Again, to add a bit of colour splash to the overall design. That colour looks like it would anchor the multi-coloured leaves nicely. (see above)
3. yes, an interlock, or overlap of the two letters at the start of the Logo would link the concept of creativity to the Brand-name Auxano, sort of.
4. Adding the multi-coloured leaves would allow a range of colours to be used in the web pages for highlighting. A 2-colour page is rather boring and difficult to create 'highlights' on. The multi-coloured leaves changes that for you.
But as I said coming into the posting, either one could work. Given the two samples provided, I would prefer the first one. Try those changes to see if any one them work to spice it up a bit. I wish I had the skills to create the changes for you as a demo.
