Mr Wimsett described his client as ``in many respects a fool who tried to keep something going which was failing''.
Judge Dawson did not appropriately take into account Cherry's remorse at his sentencing, Mr Wimsett said.
However, at sentencing in 2012, Judge Dawson said Cherry's remorse was prompted by the situation he found himself in.
A recently released judgement from the Court of Appeal has dismissed Cherry's appeal.
In their decision, Justices Rhys Harrison, Simon France and Robert Dobson said Cherry's clients were predominantly investors of relatively modest means, for whom the losses that had "catastrophic impacts'' on their retirement.
The breach of trust involved was, "if anything, more audacious'' than in comparable cases.
"It was a trust he grossly abused, particularly in those cases where he encouraged investors to borrow against equity in their homes to invest with him.''
Cherry's offending inflicted widespread and serious financial harm on a large number of victims.
"We are therefore satisfied that the starting point was entirely appropriate.
"Accordingly, the appeal against the sentence of six years and two months' imprisonment is dismissed.''
An appeal again the imposition of a minimum period of imprisonment was also dismissed.
