Hi Adam,
The CADS look good so far and a massive improvement. There are a few points though if I may:
The air conditioning vent (little square panel on the side of the cab) only featured on 56091-56135. Therefore is not accurate for the 56056-56090 range. I noticed that Dapol have announced 56059 in EWS livery and the artwork includes the vent. It would be a shame not to include an additional cab variant to portray all types.
As others have noticed, the drooping windows are quite distinctive on the class and the windows on the CADS appear to be horizontal.
The cab roof shape looks excellent. Please can you confirm whether the body width has been slimmed down as the previous tooling was quite wide and chunky looking.
If there is scope for further liveries, the following would great:
56065 Trainload Construction (un-named and would allow easy re-livery into any sector between 056-090)
56087 Colas (current)
56091 DCR Grey (current)
56107 Loadhaul (Dapol released 003 and 006 in Loadhaul previously. A Doncaster type in this livery would be appreciated this time)
56118 Trainload Coal (un-named and would allow easy re-livery into any sector between 091-135)
Cheers,
Tim
