Hi Punch
I have forgotten much of the graphology theory I learnt about 30 years ago, and disposed-of most of the reference books, but a few things stand-out from a graphologist's POV, but not knowing how you were taught:
1. Size & Proportion: average overall, with relatively high upper-zone and small centre-zone
2. Slope and Slant: a clear right slant andlines which 'droop slightly in the middle, then rise at the ends
3. Spacing: very clear and well defined, between words and lines, and a quite even left margin
4. Strokes & Pressure: hard to assess from a scan, but looks mostly quite firm, but not heavy
5. Unusual letters, Ts & Is: some looped Ts, cross-bar f low, normally dotted Is. some g loops a bit unusual
6. Connectedness: a mixture..some letter joined in groups, but quite a lot of 'breaks'
7. Signature: similar to the rest, just a little larger, not underlined, and D is different
8. Capitals: slightly unusual capital D, except in signature
9. Speed: fairly quick
10. Personal pronoun "I": normal and in keeping with other script
Now, as I'm sure you can imagine, I couldn't put that all together in just a few minutes to give a 'professional' analysis of this writer (even if I would, in a public forum!). Fortunately nothing 'sinister leaps-out at me...quite the contrary!
Suffice it to say that, boring as it usually is to most people, this appears to be the writing of a 'normal person', a quick, clear and well-organised thinker, who gets on pretty well well with others, without allowing them
too close.
His way of thinking/reasoning is a mixture of logic and intuition, and he is neither prodigal nor mean with his money.
He's pretty much a WYSIWYG, possibly a bit of an idealist (or is it a dreamer?), and quite modest.
I would not think he has more than average artisitic ability, but is more of a problem solver.
If he occasionally has 'bad days', he appears able to cope with them and to end with a smile on his face.
Although I wouldn't say if I did, I see no evidence of medical problems

Bearing in mind that it's 20+ years since I tried this, from a real sample...how did I do?
Just a bit of fun and an amusing 'parlour trick', but with a bit more scientific basis than,say, astrology
