Interesting how that quick crude sketch, probably done for a laugh, reveals something of the kind of brushwork style used in these paintings though.
As much as I admire Ancient Greek culture and history,they were quite a bunch of pederasts and degenerates.
Not actually true. It's a myth propounded by faggot scholars on the basis of extreme cherry-picking. There was a clear distinction between Platonic love and the intimate mentorship of a young man by an older man, which was extolled by the Greeks, and pederasty, which was definitely
not kosher to the Greeks. The relationship was primarily aesthetic - an appreciation of youthful strength, beauty and intelligence (where any) and the desire to help it be victorious in the world by passing on one's accumulated knowledge and experience in an intimate, loving context. It was essentially
coaching, which is still a fairly intimate relationship even today in sports (great athletes love their coaches and speak highly of them - "I owe everything to him" - and coaches love their charges, and speak of them with affection - "He's a great kid, you know").
