These are difficult questions to discuss. (It is also advantageous to attach the scheme directly in the post so we don't have to follow a link and potentially leads to a broken link if the server stops hosting the original scheme, use Additional Options…)
It is useful to see where the start and end are, but I find it difficult to comment upon a scheme. If a false step is proposed in step one, what effect does that have on the remainder to the scheme?
Was an electrophilic addition to benzene taught in class with a haloketone or as a ketal of a haloketone? I would have some anxiety about it undergoing a rearrangement by non-bonded electrons participating with the carbocation intermediate.
