One important bit of info you left out is the size of your project, from your profile your stock could be 4 foot wide BUT it could also be 4 inches wide
regardless though that is quite a complex carve & slowing the feedrate down will make a big difference. Slow the speed accordingly & start low as has been suggested.
A coat of sanding sealer an also help with chip out, if your carving 1/16" deep then it might be worth thinning the sanding sealer down so it penetrates deeper into the wood. This can help hold the fibres together & prevent chip out
