Tiller is good, and you have chosen a really good design for a hefty draw purpleheart.
I really like what you have done with the purpleheart/bocote combo. It suits the design and really lets the wood show it's natural beauty. Not sure about the artwork though. I can appreciate the time and effort you put into it, and I'm sure that wide expanse of rawhide was just begging to have something painted on it.
I find it interesting as graphic design in a print or hanging on a wall, but a bit too busy and colourful for my personal taste on a bow. I'm sure many others will disagree and that is fine. I certainly commend you for doing something different to what everyone else is doing. Looking forward to see what you do with the next one.
