The photo looks like not enough consolidation so probably a vac leak?

We wet the fabric layer by layer, with an initial layer of resin on the mould. And then the standard vacuum bagging procedure of fabric + peel ply + breather/bleeder + Vac bag. The ratio of fibre to resin for wet layup is almost 40:60 (fibre to resin) to make sure that the fiber is soaked properly in the resin pool and thinking the excess will be soaked up by the bleeder/breather (which is true as our fibre weight is 55:45 of total after curing).
