You've done very well with the pictures then.
Are you saying you don't have any means of re-sizing the pics on your computer ? You might get a bit more control over image dimensions and compression by using pc software. Also if you can do that then you can use higher settings on your camera and you will be able to experiment and see more clearly what the different pc software settings do, safe in the knowledge that there is an "undo" option. All the same, excellent pics.
p.s. agree the Morgan comparison is more suitable, but lets not forget that the British Leyland efforts only really adversely affected Triumph after/around the oil crisis when they started to detune everything in the name of economy.
