Following their defeat to Fiji, head coach Sean Lynn insisted that Wales are in a much better place than they were after the Six Nations.
Lynn, who was appointed in January, said his side showed “character and that we are being brave” during their winless World Cup campaign.
Snowsill pointed the finger away from Lynn, adding that a fair assessment of his role can only be made after the next World Cup in 2029.
“I was very, very sad after the game,” added Snowsill.
“It took me a long time to pull myself out of it. Today I have woken up, it is a fresh start and the only way is up.
“We know very clearly the areas we need to work on and we have the resources to work on it.
“It’s a fresh new cycle now, we have four years to get things right, so I’m moving on and focusing on what we need to do now.
“Let’s not forget Sean Lynn inherited Ioan Cunningham’s contracted playing group and staffing group.
“Sean has not had too much of a say in the build-up. You look at World Cups in four-year cycles, you can judge someone after they have done a full cycle.”
