Can you identify this Scottish regimental uniform

You may also be able to help pin him down by the medals/campaign ribbons he's wearing. I'm no expert, but you can look here for some help:

It looks to me like he's wearing the King's South Africa medal (though with the orange/white/green ribbon colours displayed backwards), which would indicate he was involved in the Second Boer War in 1902. That would make the painting at least from the early 1900s or later. But that's assuming I've identified the medal properly, which I don't guarantee.

I can't tell what the other one is. But it has several bars on it which would indicate he was involved in that campaign for a while. Perhaps a slight artist's misrepresentation of the Queen's South Africa medal? That might make sense, as it was from the Boer War 1899-1902, assuming he was there the whole time in his early twenties.

I think you are right on both counts.

Perhaps further information could come from the chevrons on his sleeves. Again, I'm no expert, but the internet says that the single chevron on his right upper arm denotes him as lance corporal. The double chevron on his lower left sleeve seem to have been awarded for years of service with good conduct. I'm unclear how many years would be denoted by two chevrons, but it would at least point to him having served for a while when this was painted (which of course would make sense with his campaign insignia).

"The "Good Conduct Chevron" or also "Good Conduct Stripe" could be awarded to military with the rank of Private, Lance Corporal, Lance Bombardier, Acting Corporal. As soon as the person was promoted to Corporal, the Chevrons had to be removed.

They existed in form equal to that of the rank insignia of the NCO, reversed worn on the lower part of the left sleeve. After two years the first Chevron could be obtained, after 6 year the second, twelve year the third, eighteen year the fourth, 23 year the fifth and 28 year the sixth Chevron. Six Chevrons was the maximum that were permitted to be worn."
