it looks like the bottom of the column now may be in the area of the pedals which may cause issues with them. if you did what i suggested and just angled the mount where the column bolts to the 'framework' the wheel would be lower but the column at the pedal area would be in the same place.
bolt it back up with the thin bit of wood but leave the bolts loose which will allow the weight of the wheel to lower/angle the column and wheel to where you need it.
this also makes the wheel more vertical like a vintage car. once the position is correct make an angled bracket to hold it there. it's not rocket science. all you've done is space the whole thing down but not changed the angle at all.
