The paintings he did around the mid-1880s featured a style similar to that other Glasgow Boys such as James Guthrie and George Henry, who I wrote about here and here. Later on, his style became more conventional as he turned to portraiture to earn his artistic keep.
I find his Glasgow Boys era paintings less interesting or well done than those of Guthrie or Henry. Perhaps he was paying more attention to technique than to the overall impression the paintings created.

Back to heavy brushwork.
Not all of his subjects were unknowns.
