I am assuming this isn't the finished job (just ready for pouring)? Mesh should not straddle internal rising walls, this mesh is designed for crack control only. Mesh is not complete, as pictured. You really should have perimeter edge insulation to maximise heat conservation, typically 15/ 20mm thick board, but this is entirely dependant on the shape, plan configuration of your house and insulant materials used. Kingspan can do a simple calculation and give you advice on the edge treatment. Have you considered first fix plumbing/ services- are pipes securely tied in location? If you are in any doubt you should consult an experienced builder, mistakes or omissions at this stage can be costly and later remedial work can damage insulation, DPM/ radon barriers etc. This is where the benefits of employing an experienced general contractor come into play. Other than that it looks ok, but have an experienced person look at it in person.
